According to the quarterly report from the Southern Poverty Law Center, the number of hate groups in the country has topped 1000, up 7.5% in the last year and up 66% since 2000. 35 of these groups are in Michigan. There are three broad categories of groups:
* General hate groups that target race (Klan, neo-Nazi, white nationalist, neo-Confederalist, black separatists), ethnicity, sexual minorities, and immigrants. It also includes those who deny the Holocaust.
* Patriot groups who see the federal government as their enemy based on conspiracy theories. This category has grown the fastest.
* Nativist Extremist groups that go beyond advocating for tough immigration laws to harassing suspected immigrants.
A lot of the ideas of these groups have been pulled into the mainstream (want to guess by who?). In the past that has reduced the number of these groups and their level of violence. That hasn't happened this time. The violence level has increased.
