Bryan Fischer, the American Family Association's director of issues analysis, is one of the most unapologetically bigoted public figures in the country. Fischer's notable screeds include referring to same-sex relationships as a form of "domestic terrorism" and demanding the deportation of all Muslims who are not willing to convert to Christianity. Just today, Fischer repeated his call for a ban on the construction of new mosques.

Although there's no shortage of intolerance in the social conservative movement, Fischer stands out because he also hosts a radio program, which, despite his odious record, regularly draws high-profile Republican guests. Since January, Fischer has interviewed at least six potential GOP presidential candidates.
