Since both parties are now in the thread, I think it's now reasonable to quote the post that this thread is responding-without-responding to:
WRT "lynching", I see only a statement that its use here is hyperbole (undisputed, I hope?) and the implication that an actual lynching is an injustice of an inordinately higher level than whatever forum issues started the mess.

While I don't really consider hyperbolic metaphors an "insult" to lynchees, I just don't see how implies a relation "to do with blacks or, for that matter, death", either. I mean, there's a huge array of injustices bigger than anything that goes on in a voluntary-participation forum, including, but surely not limited to, death, and none of them need be racially motivated.
