I don't think he is asking for your support... If you have a real life issue i'll agree that you shouldn't refer to a person as fat out of common courtesy, but who are you defending right now? A fictional character. Whether we like it or not, fat is always going to hold negative connotations for obvious health and sexual reasons, even if you got everyone to stop saying the word fat it wouldn't change how people feel about it. This is just reality. If that is an issue, you should advocate true body positivity through encouraging love of oneself and healthier life choices to achieve your goals.
The "fat" guy has a name: Kang-Hun.I hope the ones who call him "fat" in the comments are not using it as an insult.You sound like you're a disgusting fatphobic asshole.Being fat is nothing wrong.His attitudes have nothing to do with being fat.Just call him an asshole or whatever.Don't use the word fat as like a derogatory term.
