I would say that I have a good sense of humor. I actually don't mind fat jokes or even ones really offensive (i.e. Eric Cartman, Homer Simpson etc.) provided that they are actually funny. Now the question of what constitutes “funny” is a huge one that’s been covered on tons of literature across the spectrum of academia so I won’t go into it here. That said, I think a lot of people are way too sensitive and get offended too easily and instead need to laugh it off or to categorize it as "stupid" and walk away.
There are plenty of reasons a joke isn’t funny. It could
be in poor taste, it can be designed to humiliate or insult, or it can
incorporate racial slurs or any of a million other things.
So where's the line between joking in poor taste and actual hatred drawn? I was thinking of this because I got an article about Two Gamestops in Los Angeles who had their employees in fat suits to promote fitness games (I've written about fitness games previously, saying that you should do exercises that you enjoy, but I personally like my exercise not to waste electricity). I would categorize this as stupid as most fat suits gags are. Even if I was thin, I would think fat suits are merely dumb, but some people clearly think it’s a lot funnier than I do. I don’t get it.
I think humor ends when the jokes are pretty much meant to demean people and to remove their dignity. Shows like Family Guy, The Simpsons and
