Venting hostile nonsense in a thread to a user you don't like, keep it to yourself or take it to PM?

Either suits me fine, but it seems some feel the need to promote their own pathetic agenda. I’m not talking about folks who need “calling out” when a clear lie or error has been passed off as fact, just the few who seem to actively seek confrontation.
It adds nothing to a thread, indeed, the petty ramblings serve only to distract from the original theme.
If you can’t put up then shut up!
