Due to his trauma he judges others unconsciously, because that's what everyone did to him and eventually he started to judge himself. The character himself developed his phobia due to the constant bullying. Think of it in his shoes, he sees being fat as shameful and a sin because of the people who bullied him. Hopefully he gets over this and has some character development, but please don't invalidate his feelings.
I'm aware he is only a character, but it still upsets me. Thank you for your time.

damn you are right im so sorry for saying shit like that without putting more thinking into. thanks for telling me this! but im still kinda ... about his comment on the mc sibling like we don't need to dress "according" to our gender, ppl shouldn't assume others' gender. someone can dress feminine and be a man or nonbinary ╮( ̄▽ ̄)╭ and again thank you, i understand the character better now!! -also sorry for my bad english
