I wish that you would would qualify what you mean by "the left." The people I think that you mean have nothing to do with The Left, and in fact, has been forcing us out of their enclave. Chris Hedges has a very insightful video about them, and in it he said that they are doing the Real Left a great deal of harm, because they make those who disagree with them think that they disagree with the principles of The Left. I wish I had the link for you. He calls them the Faux Left, or "the liberal class." Jimmy Dore (who is on the Real Left) calls them "shitlibs."
They aren't "the Left"; they don't represent us; and I dislike them even more than you do.
