Social theorists are arguing that the decline of such groups is not due to a lack of belief in such doctrines, but the fact that many ultra-right wing beliefs have become more mainstream. (see the proposed Arizona anti-gay law as an example.)
Mark Potok, a senior fellow at the Law Center, says that while acts of violence and terror have declined discriminating laws have been on the rise. Major politicians have been backed by all sorts of extremists groups including, the white supremacist Ku Klux Klan, the anti-gay Liberty Counsel, the black separatist Nation of Islam, the neo-Nazi National Socialist Movement, and a host of groups including anti-Semitic organizations, anti-Muslim, and Holocaust Deniers.
According to the latest information the top states for hate groups are California with 77, Florida with 58, and Texas with 57.
