If you could write up an intelligent post arguing for progressivism, then you would probably get a lot farther on convincing the far-right faction of this site than by telling them they are evil for holding their beliefs without giving reasons as to why. (The problem, of course, is that it requires time and effort.)

It may depend on what you mean by the far-right faction-- I think the farthest right has already left. It might be more possible to move the middle rather than convince the extreme.
