What a bunch of miserable idiots.
In general, trying to make the world safe for everyone suggests an unstable personality. Fear of consequences to self = make sure that NO ONE suffers this fate.
Then again, trying to make the world sane suggests a realistic and stable personality. But such a personality would never try to control antagonism... it never has been controlled and never will be.
A smarter person might try to make different groups get along through mutual respect and separation, but that's too witty for this bunch. I like how almost none of the reggae artists signed it. Apparently, there's occasional racist comments about whitey or Asian girls, and lots and lots of homo-hatin'.
"Can't we all just get along?" is the equivalent of saying "Life made me butthurt before I was born"
