For real though, I don't see what the problem is with expressing dislike over a character. As long as you acknowledge that it's just your opinion, just say what about them you don't like, something like "I don't like how they look" or "I prefer that character over this character I don't like" and people on the other side of the view can respectfully disagree with it then it's all good. People complain about characters all the time on this thread, make up some arbitrary excuse as to why they can't join Smash bros and they get ganged up on. Hell, even the retort against these types of comments are "Just say you don't like the character." So this thread should be okay with saying who you don't like, it's just they don't like it when you try gate-keeping them.
