There are a lot more than 666 churches in the USA so who cares? Just more junk mail to throw out, I guess. He's just getting free publicity for his other movie.
I have no problem if someone wants to be an atheist. But when they make it their life goal to drag down with them as many people as they can, that's crossing the line.
And why the 666? If this guy is an atheist, he surely doesnt believe in Satan, so he's only using the number for shock value. What an attention whore.
Prayers for his pitiful soul.
