It's not objectionable, it's just impossible. Well, not completely impossible, you can do that if all you allow is pictures of food, kittens and flowers and people responding with the thumbs up emoji (actually I'm not so sure about food anymore).

No matter how rational and dispassionate an argument objectively is, someone will perceive it as violence. What happens is that "tolerance, kindness and mutual respect" becomes "protection of the moderator's ego" and adherence to an ever expanding set of intellectual dogmas.
