Maybe...but I doubt it.
Freedom of religion means just that...there are Satan worshipers world-wide...but you probably won't hear much about them...unless you live in "...only in America", where our free press can sensationalize such events.
Personally, it is not a big issue to me. America has become a country of excesses, this is probably just one example. I am much more insulted by what our elected politicians are doing than what these Satanists are doing. The politicians have the potential to do much greater damage to our society than the Satanists, who just want the same freedom to practice their "unusual" religion.
Cheers!
