It's no different than moderate Muslims having no social refuge other than where Salafist-Jihadists (eg: al-Qaeda, Isil) roam freely -- modereate conservatives have no social refuge other than blatant racists and sexists, neo-nazis, and other generally unpleasant undesirables.

This is the danger of progressive supremacy and the only way out of this hell-hole is encouraging true diversity and inclusiveness -- diversity of thought that includes right-wing conservative viewpoints in addition to those of the left.
