Tricky one there Jon - I don't think I can get my head around that.
I think part of the answer lies somewhere in history, where for years white people took black people as slaves.
But as Clarkson found out last week, no matter who you joke about, you're in the shit.
I suppose humour will die out completely one day as there is always some PC types going to take offence.
Maybe if folks stopped joking about folks that would be acceptable.
Get ready for a new breed of comedian that 1) Only jokes about inanimate objects or 2) Isn't very funny at all.
By the way - did you hear the one about the bloke with the big nose? Ooops! Sorry...
Why don't we have a contest to find the funniest joke that is politically correct? Bet the winner would be about a plank of wood
