To an extend I would. I have both left-wing and right-wing opinions, depending on the issue, it is not like I think there is only one correct opinion on issues. However, there are extremist views that I would just not tolerate. I would probably not date a radical-left wing anarchist nor a right-wing suppremecist.
This might be political incorrect to say though, but in recent years, extremism in the west has almost exclusively been a problem on the right.
