or the colours of a ducks feathers

I just watched The Foundry’s Anti-discrimination Ad on the Gruen Transfer because all of the hype made me curious. Apparently it was so shocking that it was unable to be aired on the television. Which is somewhat confusing considering the shite that is aired, such as Big Brother and adverts for phone sex.

The thing that actually offended me was the amount of warning put in place to let people know that they might be offended. Because if there was no mention of race or sexuality, and if it was just focused on the fat jokes, it would be a featured video. It offended me that we have to be so politically correct about race but when it comes down to it, if you are discriminating about a persons colour or their shape, it is still about a physical aspect of their being.
I don't see how one type of discrimination is worse than any other. Why is it ok to make fun of someone for being a woman, or blonde, or fat and not ok for the exact same things to be said in relation to a Jew or a brunette?
I think if you want to be politically correct it has to apply to everyone or no-one. There is no graysacle.
