This is pretty weird for me. I've been around long to see our (socialists of all types) collective fortunes wax and wane, alliances come and go, but we've never come to actual blows in this fashion, even when SRI and LSF were at each others throats.
Do as you will, but this won't make you any less small or irrelevant to the powers you're supporting through your actions, nor will your pretensions towards "Leftist unity" actually get you anywhere.
