Being gay is nothing new an old saying from Roman times I believe is ....

"Women are for breeding, Boys are for pleasure"

Yes I find it quite disturbing.

Making comedy out of life situatons is not new, we all laugh at people for being stupid or acting in a stereotypical manner we just call them by a characteristic ie:
You Fag, You Ginger, You paki, You woman, You black, You fatty, You old git, ect ect.

If the person is respected people usually don't look for the flaws so much and see past what ever makes them indevidual.

Gay humour is nothing differnt to any comedy it's just a genre.
