Hate groups increased in the country last year “as the radical right was energized by the candidacy of Donald Trump,” according to the annual Year in Hate and Extremism report released today by the Southern Poverty Law Center.

The nonprofit SPLC, based in Montgomery, Ala., found that nationwide, active hate groups rose to 917 in 2016, up from 892 in 2015, and an increase from 784 in 2014. The most dramatic growth was the near-tripling of anti-Muslim hate groups — from 34 in 2015 to 101 last year, the SPLC found.

According to the SPLC, 40 hate groups operated in 2016 in Pennsylvania, the same number as the year before.

“Trump’s election has been absolutely electrifying to the radical right,” Mark Potok, senior fellow and editor of the SPLC’s 2017 Spring Intelligence Report issue, said Wednesday during a conference call with reporters.

The SPLC said it documented 867 bias-related incidents, including more than 300 that targeted immigrants or Muslims, in the first 10 days after the presidential election.

Pennsylvania had the fifth-highest number of hate groups after California (with 79), Florida (63), Texas (55) and New York (47), the SPLC found.

Among the 40 active hate groups in Pennsylvania, the SPLC listed three as being active in Pittsburgh and seven as being active in Philadelphia, including three black separatist groups: the Nation of Islam, the Israelite School of Universal Practical Knowledge, and the Israelite Church of God in Jesus Christ.

In Pittsburgh, the group identified the American Freedom Union, a white nationalist group working out of Hampton, the Daily Stormer, a white nationalist and neo-Nazi website, and the black separatist group The Nation of Islam.

It listed three white nationalist groups as operating in Philadelphia: the Harrisburg-based Keystone State Skinheads, now Keystone United; the Traditionalist Worker Party; and the Daily Stormer, which last year created clubs for people to join, Potok said.

The SPLC also identified the group As-Sabiqun, an American Muslim organization based in Washington, with branches in Philadelphia and elsewhere, as another hate group operating in the city.

Potok said four groups, including the Daily Stormer, grew rapidly or were created during Trump’s nomination. Two of the other groups, American Vanguard and the Right Stuff, were listed as white-nationalist groups operating statewide in Pennsylvania. The fourth group was California-based Identity Evropa.

There were no anti-Muslim hate groups listed in Philadelphia, but the SPLC named the Shoebat Foundation as operating in Newtown, Bucks County.

Also in the Philadelphia area, the SPLC listed a group called Catholic Counterpoint, which it describes as anti-Semitic, as operating in Broomall, Delaware County.

Last year, the SPLC listed six hate groups as operating in Philadelphia: the same three black separatist groups plus As-Sabiqun, Keystone United, and the Traditional Rebel Knights of the Ku Klux Klan.

The SPLC said the number of active hate groups found nationwide in 2016 was 101 shy of the all-time record set in 2011, but still high by historic standards. The overall number of hate groups likely understates the real level of organized hatred in America, the nonprofit said, as a growing number of extremists operate mainly online and are not formally affiliated with hate groups.

Potok said the SPLC listed a hate group as being active if it had on-the-ground activity, which could involve holding rallies, committing crimes, spreading leaflets, or going out and recruiting new members.
