True, looks like his first post in the thread was actually responding to you (a post in which you were responding to / agreeing with bbb)
I disagree with your characterization of his posting in that discussion with you, wookie, and bbb as “coming in swinging” though. Even if we don’t ignore the history and potential bad blood there it seemed like it was a relatively fine discussion. Seems like those are the kinds of discussions we should expect (hope for?) on a political discussion forum. Getting back to my original point, something changed in that conversation that wasn’t present at the beginning, and it wasn’t the existence of you or wookie.
