The concept of "hate-crime" is very Orwellian. I wonder how often it's used to punish crimes against Christians.
"My impression from a discussion I heard recently is that Wicca is just old-fashioned paganism revived---nature worship."
Actually, we follow (not worship) a god and goddess of our choosing (or do they choose us?), and we see their presence in nature. We do not worship nature per se.
There are white Wiccans like there are white, uh, lawyers, I guess--those sworn to seeking out justice for the downtrodden and always fighting the good fight.
Then there are those Wiccans (like me), who are more pragmatic.
