My guess is there are even more anti-Muslim hate groups then reported:
The Southern Poverty Law Center has published the Spring 2012 issue of its Intelligence Report, on “The Year in Hate and Extremism 2011”, which identifies a continued growth in the number of hate groups operating in the United States.
In “The ‘Patriot’ Movement Explodes” Mark Potok states: “The radical right grew explosively in 2011, the third such dramatic expansion in as many years.” Potok writes:
The number of anti-Muslim groups tripled in 2011, jumping from 10 groups in 2010 to 30 last year. That rapid growth in Islamophobia, marked by the vilification of Muslims by opportunistic politicians and anti-Muslim activists, began in August 2010, when controversy over a planned Islamic cultural center in lower Manhattan reached a fever pitch. Things got worse later in the year, when Oklahoma residents voted to amend the state constitution to forbid the use of Islamic Shariah law in state courts – a completely unnecessary change, given that the U.S. Constitution rules that out. The overheated atmosphere generated by these events also helped spur a 50% jump in the FBI’s count of anti-Muslim hate crimes in 2010. Then, in March 2011, U.S. Rep. Peter King (R-N.Y.) held hearings on the radicalization of U.S. Muslims that seemed meant to demonize them. At the same time, there was a swelling of truly vicious propaganda like this remarkable Jan. 14, 2011, comment from columnist Debbie Schlussel: “They are animals, yes, but a lower form than the dog, as they won’t learn to change their behavior for a carrot or a reward.”
In connection with anti-gay groups Potok points out:
In another development, most of the religious right groups that started out opposing abortion but moved on to attacking LGBT people have recently begun to adopt anti-Muslim propaganda en masse. The gay-bashing Traditional Values Coalition, for instance, last year redesigned its website to emphasize a new section entitled “Islam vs. the Constitution,” published a report on Shariah law, and joined anti-Shariah conferences.
