Let's not even put the word "like" in this situation. These bullies saw Chamin as different and therefore beneath them, so they did the worst thing they could think of to try and prove that Chamin is powerless and they are "superior". I know that BL likes to take the whole "he bullies you because he likes you" to extremes, but let's not make that our first response to this.
I think you misunderstood what the other commenter was saying. The main bully guy was probably confused about his OWN sexuality and was projecting. This happens often (unfortunately) the "self loather" will become angry at their object of affection and instead of trying to sort out their own feelings they will lash out at the other person. The word "like" DOES apply here. Just because a person responds with violence doesn't mean they don't like the person it just means they don't know how to handle their own feelings. Not every act of violence is done out of "hate" humans emotions are far more complicated than that.
No I didn't misunderstand. I wasn't trying to invalidate their claim that one of those bullies could be a closeted gay. It definitely wouldn't be the first time this has happened in a bl manga or real life. I just think it's interesting how that's one of the first thoughts blindbandit shared after what we were shown and I think it's sort of telling about what we expect and have seen from BL. I don't think I chose my words carefully enough in my original response. Hopefully this helps clarify my thoughts a bit.
I bet those damn bastards liked him and were too stupid (very very stupid) to admit it. It makes me want to swear so badly when some people resort to violence when they're confused about their feelings. I'd wish there was an app/device where they'd be the one to feel the the pain if they violate someone or punch them. Wait there is in black mirror but damn I wish it was real ╥﹏╥
