They'll tell you ''we don't have to be tolerant of intolerance!'' (see the first reply to this thread, for example). Of course, to them, ''intolerance'' is pretty much any disagreement with their cultural agenda whatsoever.
A statement or position is not automatically wrong because it strikes leftists as ''intolerant''. Leftists are not the sole arbiters of morality, and there's good reason to be intolerant of their cultural agenda.
This is true, though I understand from a secular humanist worldview why leftists see things the way they do. I reject this paradigm, hence why I disagree with their philosophy.
