I don't think there needs to be. The strength of the left is also its weakness. It is monolithic. If enough people attack it from all sorts of directions, it'll crumble.
What we see is a facade - the paint over the monolithic group-think of a minority of the public. They happen to have the megaphone, that's all. They have been outnumbered all along. The problem with our side is that we fall for the illusion.
