You took this to a whole other discussion. Yes there are some people that think fat "should be beautiful" and those people are fooling thenselfs more than the others.

But this is not the majority a neither has been pushed "for years". This began with the woker culture trying to humanize fat people exactly because of how bad people are treated just because they are fat. But I can tell you I don't know any fat person that thinks like that. Like most (not all) very skinny people have some eating disorder, most (not all) obese peoole have some eating disorder, this can be in consequence of depression, addictive personality or even in conquencence of medication that they need

That is why is so important to no judge someone without knowing why they are in this situation.
