Something can be funny, and either be PC or not PC.One doesn't necessarily have to be PC to object to tasteless humor.
If indeed it was funny at all.
And then something can also be not funny, whether it's PC or not.
The disabled comedian that I mentioned in my post above - I didn't find him overly funny. And I wouldn't have found his jokes overly funny whether or not he was disabled. It wasn't whether they were tasteful or not - I found some of his humour a little amusing but overall I just didn't find his jokes very good, or very funny.
Others obviously disagreed with me, and found him genuinely funny.
But then there would have been a percentage of those who found him funny who would have NOT found him funny if he'd told the same jokes but not been disabled.
If he'd been an able-bodied, non-disabled person, putting on an act of being disabled to tell the same jokes, then suddenly his same jokes would have been considered by some to be insensitive and derogatory toward the disabled, and tasteless, etc etc. And instead of getting bookings with high profile media shows and even disability organisations, he would have got a heap of bad press and public lectures on how hurtful and politically incorrect he and his jokes were.
So those are the hypocrites and those are the people who are really doing the discriminating. If they were honest with themselves, they would find the humour either funny, or not funny, regardless of the person. If they only found the humour funny when they knew the person was disabled, then if they were honest with themselves, effectively they were really only laughing at the disabled man telling disabled jokes. Did the fact that he was disabled make the jokes funnier, or did the fact that he was disabled remove any feelings that it was 'wrong' to laugh at, and about, the disabled?
That hypocrisy is the same whether it's humour about disability, race, religion, or anything else.
I don't know if that made sense, but it's essentially my long-winded way of saying I agree with Gob's comment, copied below.

Here's the nub though, if it's funny, but not "PC" is it still funny? I'd argue, as others have, that the automatic condemnation for any humour which involves some aspect of race, is unwarranted, and only stirs up trouble.
