Europe’s infamous ‘no-go zones’ are coming to America. At least they will if ordinary Americans don’t stay vigilant and fight back against the mass migration and political correctness being foisted upon them by establishment politicians and their left-wing hate-mobs.

Here are four key indicators you can watch out for to make sure your neighborhood stays American.

Who’s Moving In, And What Are They Doing There?

Muslim migration in large numbers into Europe has brought with it a scourge of ills, including dependency, rape gangs, and Islamic extremism. It’s no use denying these things. It doesn’t help anyone to pretend the Cologne migrant sex attacks were fake, or that the Rotherham rape scandal never happened.

The first thing to look out for is whether or not people are productive immigrants. Are they working? Do they have jobs? Or do they coalesce in cafes or on government housing estates all day – idle enough to be prime targets for radicalization?

In some of Europe’s no-go zones, men will shuffle back and forth between mosque and town center, scarcely having to worry about income. Western governments take care of everything for them. From housing to hand outs, it suits the political ends of the Left to keep people dependent and keep people in poverty.

Halal Here, Halal There, Halal Everywhere

One of the things needed to make an area opportune for takeover is a prevalence of halal meat. This is food slaughtered by the traditional Islamic diktat, where the animals suffer intensely. Undercover reports have revealed that conditions in some halal abattoirs are nothing short of disgusting.

Some people will wonder what the difference is between halal slaughter and Jewish slaughter methods like shechita. The truth is: many. But the main one is shechita effectively stuns the animal as it is killed, whereas halal butchers tend to have much shoddier methods.

And where is your money going when you buy halal, anyway? Talal Chahine, the owner of the La Shish chain of restaurants in Michigan, may know. In 2006, Talal Chahine was reported to have evaded taxes while funneling some $20 million to the Lebanese terrorist organization Hezbollah.

It’s one thing for Muslims in America to be able to get the meat they prefer to eat, but when conditions are so bad for the animals you’d think leftist groups like PETA might have something to say about it. Furthermore, it is a whole different matter when halal gets hegemony, as is the case in many areas of London and Paris.

Hijabs, Niqabs, and Burkas

The argument as to whether the veil is Islamic or not is one that will rage on for years. What is more clear, however, is that when burkas start becoming the norm, when you’re more likely to see someone with only her eyes on display than someone rockin’ a pair of daisy dukes, then you know something’s up.

It’s hardly likely that any self-respecting person would want to cover up like this – despite some protestations from hard-line Islamic activists. In truth, there is a strong element of coercion, force, and in some cases threats behind enforcing this “modesty.”

Remember: even Muslim women in the Middle East have resisted head coverings for decades. In Iran in 1979, one hundred thousand women protested against the hijab. In Egypt in the 1950s, the leader of the country laughed at the Muslim Brotherhood’s demand that all women should cover up. Even this year, in 2017, Syrian women celebrated the liberation of their towns from Islamic State control by burning their burkas. So why are we so flippant about it here? And where are the feminist voices demanding internal, Islamic parity for women with men?

More Mosques Than You Can Shake a Stick At

This isn’t to say all mosques lend to Islamic radicalism or the onset of a no-go zone, but it certainly means the area is changing irrevocably.

Knowing the difference between an Ismaili mosque or an Ahmadi mosque versus a Deobandi mosque or a Salafist mosque is very important. In fact, more often than not, groups like the first two will want to integrate.

But watch out for places like Hamtramck, Michigan, where Sunni hardliners play the Islamic call to prayer out on the streets. They have a majority Muslim city council, so protests land on deaf ears. In a city of about 2.1 square miles, one estimate says there are up to 17 mosques. Another says 12. That’s a lot of mosques.

They cater to different Islamic sects, of course, so it’s not like they can all just merge into one.

But the prevalence or even dominance of Islam in these areas is often a sign that the local communities are highly insular. Many housing estates in no-go zones boast satellite dishes on every balcony so residents can watch foreign-language television and not English broadcasts.

These are just a few of the things you can watch out for to see if your neighborhood is being transformed into an insular ghetto. Of course, there are exceptions across the world, such as the bustling and welcoming neighborhood of Edgware Road in London.

But broadly speaking, if you’ve noticed an uptick of these factors where you live, you might just be living in a future no-go zone.
