In order to understand the whole situation and especially what's Rintaro is saying about his appearance, we need to understand that Japan is a homogeneous society. It's kinda hard to wrap my head around the whole conflict between the two schools, cause for sure there are bad apples in every school but you don't demonize the rest of the students because of them. Maybe it's not so far fetched considering the Japanese societal view of being associated with something bad = you're also bad. Idk, maybe it's just the manga....
