Yes my humour must be offensive 
, because I pointed out to you that it wasn't funny, I found it incredibly offensive as did another poster, you also don't know me, nor do you know the majority of people who use mumsnet, I don't know you, I never once said I did,its also completely irreverent also, its NOT acceptable to make fun of those who have no choice in having a disability! I also didn't say you we're a hating disablist etc... I pulled you up on making fun of people who have this learning disability, do you honestly think its "fun" or "joke" worthy to call people who struggle with this disability "thick" for humour, evidently you do!, or else you wouldn't have made the extremely offensive comment
I have a right to pull anybody who think this disability is for humour, or thinks that people who suffer from it, are "thick"
I think you do knows it was a unacceptable comment, hence why you've further went down the obscenity and back up route, instead of just apologising,you've just made yourself look like a disablist fool, and that's what I find sad, because you see nothing wrong with your attuide, even when those who do have this disability have found it offensive to us, and those who have the disability.
