This "pleases the group" that experiences harassment. Are you in favor of harassment? Or against protecting those who experience it?

If that's not a problem for you, and if your "common sense" makes you a nice person, these rules don't affect you in any way. However, my "common sense," which you don't seem to share, tells me that communities with explicit anti-harassment guidelines do better in creating a positive, smart, collaborative environment.

For example, on HN we rely on explicit guidelines for polite conversation and not on some implicit sense of common sense. Without those guidelines the conversation devolves into well... harassment, name calling, trolling etc. (See any unmoderated forum on Reddit).
