I didn't suggest you were being impolite. I said you didn't back up your stance so we can't judge whether it's incorrect or not. It's literally just an assertion you made without any attempt to back it up.
The obvious potential error in your stance-- again, which you have not even attempted to support-- is that this was to prevent "disagreements". Can you support that? Do you make a distinction between a disagreement and trolling and harassment, or are all of those lumped together for you?
C'mon man; you cared enough to make the assertion, support it.
