Extreme Liberal took the time to transcribe a podcast rant by Chez and me about the firebagger/professional left. Not to toot our own horn, but it's definitely worth reviewing (here and cross-posted at Angry Black Lady).
If you're looking for a summation of why we think certain players on the left are hurting the progressive movement, this is a good source. I think we covered just about everything and took a full 30 minutes to do it (in real time).
