I believe one should make an effort to tolerate others' beliefs, as long as they're not being forced on anybody else. And when the same religion can produce Raoul Wallenberg and Jack Chick, it seems inadvisable to judge a faith en masse; much better to take each individual on their own merits.
That said, I can't help but view some faiths as irredeemably
silly, and
LaVeyan Satanism is high on that list. It's not because of its values - which I haven't really examined in detail - but because building a religion around somebody else's Adversary is the same sort of lame as listening to Marilyn Manson because your parents hate it.
Nice irony here:
"Satanists are encouraged to perform devil worship rituals, to fulfil their sexual desires and to change situations or events in accordance with their will. Leading hand Cranmer, 24, is single..."
