Exactly. Mocking people like George Clooney and Leonardo Dicaprio because they date people much younger than themselves is very different to mocking someone's health issues. I've seen most of Ricky Gervais's ceremony gigs and don't remember the celeb jokes being against someone's health like that (maybe someone with a better memory can quote some).Sorry but I think there’s still a line which shouldn’t be crossed, even when mocking celebrities, and I’d put genetic disease well and truly over that line. Would it have been acceptable to mock her if she had to use a wheelchair? Or for the colour of her skin? Or her gender? Or are these things fine because she’s a celebrity?
And comparing a woman's hair loss with a man's hair loss is obtuse.
That's not to say I condone what Will did, it was a stupid reaction.
