That may be so, but the denigrate (and common case as this thread suggests) is to expand the notion to any offensive speech that is disliked by the offended person. That is much more subjective and hard to define. The fact that we have some (better) definitions doesn't really help. The desire to censure speech is widespread, for different reasons, many conflicting. And the fact that there might be a rough academic consensus on where to draw lines (at least theoretically if not practically) isn't good enough in practice to actually define clear rules.
