How are wife beaters allowed in this subreddit yet constructive criticism is not?

One of the members of this subreddit u/abwehrstelle made a post about beating your wife. And no, not the beating mentioned in the Quran. Beating with fists. Yet his post is still up and he's not banned. However, if you dare to share some constructive criticism and provide citations as brother u/AConcernedMuslim did, you are banned immediately, no questions asked. This behavior is very telling of what this subreddit stands for. May Allah guide you all and protect the women in your life.
