Cheers, Phil. Not a pleasant rabble at all. You are wise to know to keep your distance. Their only benefit to you is that you can certainly see and smell them coming. So an alleyway will have a warm light, but that can sure be close-quarters!.... Maybe it's "I don't want to meet them in a confined space!"
Well, it's kinda like the metal scene. Some of the nicest people I've ever met are metal-heads. and they look out for each other in the mosh..... I think the nice, positive attributes I/you/others display comes from getting out that aggression or frustration through our arts..... Or it could be I'm just a nice guy and this style is a fun strong point in my craft!
