Even if all that is true, "you're being obnoxious to the highest degree" counts as name-calling in the sense that we use that term here and it's not a borderline call. You can make your substantive points without that kind of thing, so please do, regardless of how bad other comments are or you feel they are. Everyone always feels like the other person started it and did worse, so if we rely on those perceptions. we're guaranteed to end up in a downward spiral.
