That was the next thing I was wondering about. Will there be some "visited your profile"-marker or whatever so that somebody could be "innocent" because he did actually not visit the profile or will that visit just be mandatory before commenting on a post?
One fair option is to outlaw pronouns in the entirety. While this is largely absurd it solves for any and all related problems of emotional distress equally to all people.
More seriously though, at one point is catering to somebody's offense the line too far? I am really of the mind that online posts that voice offense or defensiveness should be flagged. To me offense is a lazy way to discard disagreement when remaining objective or simply walking away are more effective.
