I was going to ask about that. One of the thoughts that occurred to me was the distinction between being offensive and being threatening. That which is offensive is to some degree subjective, whereas that which is... As well, we see reversals of valence on this sort of thing; the 8th Army called themselves the Desert Rats. Originally that was a term of disdain, and they said that they kind of liked it.
Offensive is to some degree subjective, whereas threatening presumably is measurably objective. If I threaten to beat someone up as opposed to threatening to kill them, as opposed to threatening to burn their house down, those are three distinct types of objectively definable offences. I'm wondering about your thoughts on that.
