The wacky derivations of their beliefs doesn't change the fact that most businesses in red states would kick you straight out the door for antisemitism or any criticism of Israel. Anti-semitism is far outside the mainstream anywhere in the country you choose. The closest you'll find to mainstream overt antisemitism is probably Idaho, but even there it is very fringe. You'll be hard pressed to even find a church that accuses Jews of killing Christ, while a century ago this was common doctrine. The American public at large no longer tolerate this sort of thought.
