I think I am going tom have to agree with bum here.
While it think the recently posted thread labeling Chappo a homophobe, is taking it a long way too far, certainly I don't think that pointing out that in this thread, the line between funny and offensive was in danger of being scuffed out by footprints.
I think that in general, its good to be able to have a joke, and even jokes at other peoples expense - but it's also good that those jokes are generally acknowledged as treading on sensitive ground. I for one don't want to go back to the days when abo jokes, poof jokes, wog jokes etc were acceptable without consideration. They should be considered, and mostly, they should be considered better left unsaid.
Like it or lump it, the line between funny and offensive has been crossed the minute someone actually gets offended. The only thing up for debate is whether you care or not.
