Sixteen hate groups, including neo-Nazis, anti-gay churches and even a music label, operated in Colorado last year, according to the Alabama-based Southern Poverty Law Center.

Colorado saw five new hate groups operating in 2015, but the state had a net gain of one group last year, said Mark Potok, senior fellow and editor of the organization’s Intelligence Report.

Other groups folded for various reasons, Potok said. He did not know which Colorado-based groups fell off the list from 2014.

Nationally, hate groups grew 14 percent in 2015, up to 892 from 784, the law center reported Wednesday.

“While the number of extremist groups grew in 2015 after several years of declines, the real story was the deadly violence committed by extremists in city after city,” Potok said.

“Whether it was Charleston, San Bernardino or Colorado Springs, 2015 was clearly a year for deadly action for extremists.”

In Colorado Springs, Robert Lewis Dear stands accused of killing three people, including a police officer, during an armed assault on a Planned Parenthood clinic. Dear said in court that he is a “warrior for the babies.”

But Dear has not been identified as a member of a hate group by law enforcement.

Still, Potok said the messages sent by extremists influence people such as Dear and Dylan Roof, the man accused of killing nine people inside a historically black church in Charleston, S.C.

Of the new groups added in Colorado, Potok said, analysts were not sure where two of them — neo-Nazi groups — are based. Those groups are the National Socialist Movement, a group headquartered in Detroit and known for its provocative political action, and the Wolves of Vinland.

The other new groups were:

• The Friendship Assembly of God, a church in Colorado Springs that teaches falsehoods about lesbian, gay, bisexual and transgender individuals.

• The Colorado Alliance for Immigration Reform, a Lakewood anti-immigrant group.

• Israel United in Christ, a Denver black Hebrew Israelite group that is anti-white.

The Southern Poverty Law Center researches hate groups throughout the year. Groups make the list based on their ideologies and their activity, such as meetings, rallies or selling paraphernalia, Potok said.

Churches are not listed as extremists because of their biblical beliefs, he said.

They make the list once those beliefs lead them to teach falsehoods or to defame others.
