I don't see much hostility at all. A few people don't like them. That's not weird hostility, isn't it just self-expression? Like the stickers that oppose or express a dislike of something, which presumably aren't weird hostility either. People are allowed to dislike or disagree or make not entirely positive comments. Sure some would just scroll on, arguably that's the better thing to do, but commenting in self-expression is really fine too. It seems like a strange kind of fragility and inability to tolerate or understand that people don't all think alike which would jump to thinking that is "hostility".
