Sounds like one more attempt to break taboos just for the fun of breaking them. Personally I've never understood hating any group of people for any reason. It's uncivilized, it's childish and most of all it's degrading your own intellect. I don't really like people in general, but it has nothing to do with who they are and has everything to who I am (I'm not a very social personality).
As a sidenote, I'm happy there aren't any "LHP" groups here where I live in the way UV mentioned. Everyone I've met are very much like the ones here in the DIR, very... could you say moderate? in their beliefs. I've had a hard time being accepted by my family and friends as it is (even without any labels), and with groups like JoS I could give up all hope of ever getting to a point where I can openly be who I am.
Back to topic, kind of at least. I do know a guy who claims to be a Satanist, who goes around causing mischief (like turning over tombstones) and being openly a racist, but he's really young and seems to be more about rebelling than actually practicing any religion.
