Please ping people if you are going to badmouth them.
Concerning the comment you highlighted...
If people don’t want to be badmouthed, they should alter their behavior.
They shouldn’t think they can come on the forum and act like an ass, and that others should then act as if they haven’t been, by affording them respect.
If I mention someone’s name, I’ll address them directly or ping them.
If I just address the behavior, tough luck.
Don’t set your behavior up to be ridiculed, and you won’t be disappointed.
