Mh... actually, you're right on a lot of things.
Especially saying there are FAR worse things to worry about than people being fat (which can mean EVERYTHING, because really, one can be fat in various degrees and not every single one of them is dangerous for their health, and I really doubt society is SO touched by it anyway).
But I still don't see how they make fun of her. I mean, I see how they try to make the video funny, but not really at her expense.
If I got your opinion right, I think you mean they are trying to show fat people can be happy, like it's supposed they usually aren't. I don't know if that was the purpose behind it, I personally was just glad I saw a person with a different appearence behaving just normally, for a change (much like I enjoyed a lot Woman's World video by Cher, because it displayed a lot of variety of women having fun in the same way).
