But can you always "count" on a person's enmity, or should you? I don't mean this person in particular. Even when you have a falling out with someone, is it not better to hope that things can someday be put right? Making these sorts of posts seems to be a kind of "We are officially enemies" statement, which definitely puts constructive discussion at an end, and perhaps even encourages outright hostility.

You replied to carlanime that you hoped the trouble will not spread. Doesn't this sort of post inspire trouble? Won't people who have you both friended feel uncomfortable?
