I think your first paragraph in particular really nails one of the big problems of the modern left in the US. If you haven't, yet, I recommend reading I Can Tolerate Anything but the Outgroup: http://slatestarcodex.com/2014/09/30/i-can-tolerate-anything-except-the-outgroup/ http://slatestarcodex.com/2014/09/30/i-can-tolerate-anything... It raises, I think, some very interesting points. Not so much in the way you may agree with it or not, but in terms of how to frame the problem itself.
