fat jokes about Kirstie Alley on Dancing with the Stars

I think we all need to lighten with this PC nonsense. Comics like George Lopez have been doing what you guys perceive as crass/insulting for years. It's the nature of the business. Everyone is just dying to be offended and jumps at the opportunity of defending someone else when they take umbrage. There's a great documentary with Joan Rivers out where she's doing her standup and makes a deaf joke by bringing up Helen Keller.
A man in the audience takes offense and states he has a deaf son. She tore into him by saying, "Oh, please. You are so stupid. Comedy is to make everybody laugh at EVERYTHING and deal with things, you idiot. My mother is deaf, you stupid son of a b****. Don’t tell me! And just in case you can hear me in the hallway [as the man presumably leaves the performance], I lived for nine years with a man with one leg. Okay, you ahole? I was going to talk about what it’s like to have a man with one leg, who lost it in World War II and never went back to get it because that’s f****** littering.”
At first, my wife and I were shocked with her, however, she makes a point. Why should some people be excluded from comedy?
It's ok to laugh at a joke about the random dumb person who cuts you off on the freeway, but anyone with an affliction is off limits. If people want to choose pity, do so. I think inclusion is the best form of respect and in a healthy, self confident society, blue humor can be accepted. We deal with enough stress in our workweeks. Fostering new stress over JOKES is beyond inane.
Kirstie Alley is huge and has struggled with her weight. She's also used that to help profit. Good for her. I love fat jokes. I love all humor. We all should give it a try and refrain from policing what we don't find funny.

So because it is labelled 'comedy' it is ok to make fun of someone with a disability? If comedy is to make everyone laugh are the disabled really enjoying jokes at their expense?

Just curious.

ive known several disabled people that thought jokes about disablities where hilarious,so what can people joke about?
I guess women is off the list or men or politics,or religion because all of that could possibly offend someone.
I once dated a guy whos mom was in a wheelchair most of her life and she used to tell some really funny jokes about it.
then of course there are the people in life that are way to sensitive.words only have power if we give them power and a joke is a joke
how do you think lyndsay lohan , paris hiltion,or others feel about being the subject of many many jokes I dont here people being all up in arms about that.
