Hmm, I've heard of this kind of thing but I'm glad to say that I don't do that. That and it's good that it's being brought to attention before anything big does happen. The ASPCA can be ruthless, which is good.
I may be way behind on this one but: Hell, emotional pain can hurt just as much as physical pain. Just matters in the way it's delivered. Personally, I've been pissed off enough at myself that I've actually kicked my own ass before. Sad right?
Hmm, doesn't sound like it was a good idea to me. You never know who the news might spread to then. You may not mind until people start getting on your case about it and start calling you "Faggot". Trust me, I know what it's like...Sucks.
