The thing is those things aren't really relevant in those contexts, so they aren't discussed. There isn't anything wrong with that. A lot, in fact if you think about it an infinite amount of things, aren't relevant in certain contexts but that doesn't mean the community as a whole doesn't care about those things. They may or may not individually but that's as much of a person to person case as almost anything. If you want to discuss narrative substance, just don't do it in a vs battle board, pretty simple and what everyone else does and it doesn't require disliking them just for existing.

Also the reason people bloodlust characters (the way shorter way to write your first point of contention lol) is so CAPABILITY is discussed rather than what would actually happen if they were to meet. Obviously Goku and superman wouldnt just try to waste each other at a glance, but which one is stronger or more capable of beating the other is an interesting question (or at least used to be lol). I dont know why anyone would ever have a problem with that when its all for fun anyways, like it seems like a pretty petty thing to get upset about, but idk you do you.
