1) “Muslims account for only about 1 percent of the U.S. population but account for about half of terrorist attacks since 9/11. That means Muslims in the United States are about 5,000 percent more likely to commit terrorist attacks than non-Muslims.” -- Mark Krikorian

2) “Consider, for example, that in 1958 a mere 4 percent of Americans approved of interracial marriage. By 2013, that number had grown to 87 percent. In 2012 these once-taboo unions hit an all-time high.

Ku Klux Klan membership has shrunk drastically from millions a century ago to fewer than 5,000 today. The Black Panthers are essentially extinct. While plenty of other hate groups have attempted to fill the void, they have always operated on the margins of society. Black politicians are now common—President Obama’s percentage of the white vote was almost perfectly in line with that received by other recent Democrats, all of whom were white.

Granted, these statistics offer but a snapshot of American society, but the more one looks, the more a trend emerges. America is a lot of things; racist isn’t one of them.” -- Greg Jones

3) “The harsh reality awaiting these low-income Americans is undeniable: according to 2013 data from a 2014 Merritt Hawkins study, 55% of doctors already refuse new Medicaid patients. According to the HSC Health Tracking Physician Survey, 2008, the percentage of doctors that refuse new Medicaid patients dwarf by about 8 to 10 times the percentage that refuses new private insurance patients.

Such ‘insurance’ from Obamacare not only fails to provide access to doctors, but research in the top medical journals such as Cancer, American Journal of Cardiology, Journal of Heart and Lung Transplantation and Annals of Surgery, show that Medicaid beneficiaries suffer worse outcomes than similar patients with private insurance ... all at an added cost of another $800 billion by CBO estimates to taxpayers after the decade.

It is not hyperbole to call Medicaid a disgrace at its annual cost of about $450 billion, and expanding it rather than helping poor people buy private insurance is simply inexplicable.” -- Scott Atlas

4) “In other words, all of the disruption, spending, taxation, and premium hikes in Obamacare has only reduced the percentage of U.S. residents without health insurance by 2.7 percentage points, from 13.9% to 11.1%: a remarkably small reduction, and far lower than what the law was supposed to achieve.” -- Avik Roy

5) “Bernie Sanders thinks you can pay for an 18 trillion dollar expansion of the welfare state — to make it align with a Denmark that doesn’t actually exist — simply by taxing ‘the billionaire class.’ There are 536 billionaires in America. Even if you confiscated everything they had — which, by the way, would surely destroy the American economy by triggering the greatest round of capital flight in human history and amount to government seizure of countless businesses — it wouldn’t come close to covering the tab of Sanders’s proposals.” -- Jonah Goldberg

6) “In 2010, 38,329 people died from drug overdoses, twice the number a decade earlier. More people died of drug overdoses than from automobile accidents (30,196), murders (13,000) or gun accidents (700).” -- Ann Coulter

7) “Between 1979 and 2010, for instance, the average after-tax income for the poorest quintile of American households rose from $14,800 to $19,200; for the second-poorest quintile, it rose from $29,900 to $39,100. Meanwhile, per-person antipoverty spending at the state and federal level increased sixfold between 1968 and 2008 — and that’s excluding Medicare, unemployment benefits and Social Security.” -- Ross Douthat

8) “Just last month, the Senate Judiciary Committee received a report that in just four years, 121 illegal aliens who had been released by ICE went on to murder Americans.” -- Mark Krikorian

9) “Officially known as the Supplemental Nutrition Assistance Program, or SNAP, the food-stamp program has become the country’s fastest-growing means-tested social-welfare program. Only Medicaid is more expensive. Between 2000 and 2013, SNAP caseloads grew to 47.6 million from 17.2 million, and spending grew to $80 billion from $20.6 billion, according to the Agriculture Department. SNAP participation fell slightly last year, to 46.5 million individuals, as the economy improved, but that still leaves a population the size of Spain’s living in the U.S. on food stamps.” -- Jason Riley

10) “Pace Mr. Obama, the state-prison population (which accounts for 87% of the nation’s prisoners) is dominated by violent criminals and serial thieves. In 2013 drug offenders made up less than 16% of the state-prison population; violent felons were 54% and property offenders 19%. Reducing drug-related admissions to 15 large state penitentiaries by half would lower those states’ prison count by only 7%, according to the Urban Institute.

In federal prisons—which hold only 13% of the nation’s prisoners—drug offenders make up half of the inmate population. But these offenders aren’t casual drug users; overwhelmingly, they are serious traffickers. Fewer than 1% of drug offenders sentenced in federal court in 2014 were convicted of simple drug possession, according to the U.S. Sentencing Commission. Most of those possession convictions were plea-bargained down from trafficking charges.” -- Heather Mac Donald

11) “The conservative Heritage Foundation estimated unlawful immigrant households paid $39.2 billion in 2010, but received $93.7 billion in government services.” -- Oliver Darcy

12) “On Wednesday, a Washington Post article announced that ‘The San Bernardino shooting is the second mass shooting today and the 355th this year.’ Vox, MSNBC’s Rachel Maddow, this newspaper and others reported similar statistics. Grim details from the church in Charleston, a college classroom in Oregon and a Planned Parenthood clinic in Colorado are still fresh, but you could be forgiven for wondering how you missed more than 300 other such attacks in 2015. At Mother Jones, where I work as an editor, we have compiled an in-depth, open-source database covering more than three decades of public mass shootings. By our measure, there have been four ‘mass shootings’ this year, including the one in San Bernardino, and at least 73 such attacks since 1982.” -- Mark Follman

13) “As Pew Research cheerfully reports, previous immigrants were ‘almost entirely’ European. But since Kennedy's immigration act, a majority of immigrants have been from Latin America. One-quarter are from Asia. Only 12 percent of post-1965-act immigrants have been from Europe -- and they're probably Muslims.

Apparently, the ‘American experiment’ is actually some kind of sociological trial in which we see if people who have no history of Western government can run a constitutional republic.

As of 1970, there were only 9 million Hispanics in the entire country, according to the Pew Research Center. Today, there are well more than 60 million.” -- Ann Coulter

14) “No fewer than eight major studies from around the world have found homosexuality is not a genetic condition.

Peter Sprigg of the Family Research Council says that these numerous, rigorous studies of identical twins have now made it impossible to argue that there is a ‘gay gene.’ If homosexuality were inborn and predetermined, then when one identical twin is homosexual, the other should be, as well.

Yet one study from Yale and Columbia Universities found homosexuality common to only 6.7 percent of male identical twins and 5.3 percent of female identical twins.

The low rate of common homosexuality in identical twins – around six percent – is easily explained by nurture, not nature.

Researchers Peter Bearman and Hannah Brueckner concluded that environment was the determining factor. They rejected outright that ‘genetic influence independent of social context’ as the reason for homosexuality. ‘(O)ur results support the hypothesis that less gendered socialization in early childhood and preadolescence shapes subsequent same-sex romantic preferences.’

‘Less gendered socialization’ means, a boy was without a positive father figure, or a girl was without a positive mother figure.

In light of the evidence, Sprigg said simply, ‘No one is born gay.’” -- Mark Hodges

15) “Over the last year, only 1.3 million Americans of working age have entered the workforce, even as the population of this same demographic increased by more than 2.8 million. Just over 1 million members of this group found jobs. That's right -- of the new additions to the working age population, less than four in 10 found jobs.

The newspapers touted the reduction in the unemployment rate to 5.3 percent as a cause for celebration. Yet for every three Americans added to the working age population (16 and older), only around one new job (1.07) has been created under Obama. At this pace, America will soon officially have a zero unemployment rate. But that will only be because no one will be looking for work.” -- Stephen Moore
