Where I see trouble in this is when the Satanist's ask for support or some other extreme group.
Lets say that a group forms with a belief system that uses human sacrifice.
But, I'd bet we would not tolerate such a group and would find a way to stop them from operating. All these, I consider mainstream. I don't even know enough to say or even make a guess. Personally, I'm not aware of anything that would prevent them from obtaining funding from W's programs. I find it puzzling that there is a really strong hatred of religion among a few members of this group.
