But when LGBT people get angry at people for accidentally "misgendering" them, or when they intentionally try to put people into difficult situations as some political statement, etc., then they're being assholes.
This is perfectly true, people are people, and there will be idiots in any group of sufficient size. But we need to be aware that the other side of this is true as well, there are people who dislike concepts such as gender fluidity or homosexuality, and will cite individual examples of LGBT people being assholes in an attempt to argue that this non-representative minority is actually the norm, and they are all like that.
