In Europe I've heard a lot of comments after the Brexit that the voters of the Leave camp were "aging", "countryside" or "racist". Very few people view them as possibly having a rational reasoning. "We" try to assign them a reason for being irrational.

Whether we associate Soviet dissidents with "schizophrenia", people we don't agree with with "senility", or associate undeserved moral standards with "leftists", I reckon treating someone's vote as a consequence of their weakness and not as a consequence of their decision is ugly.
