Correct. The left, in its current form, is a fairly new thing. Of course there have always been people who were more leftist by the standards of their time, but there was a concerted effort to use the universities and media to CREATE this current batch of leftists and it was successful.
They talk about how divided the country is, but the reason it used to be more unified was that everyone in the western world used to have ideas about women and men, racial groups, borders, immigration, social arrangements, abortion, pornography, etc. - which would make Trump look tame by comparison.
The modern left are the ones who diverged from that. They really shouldn't have the right to complain about a divide when they are the ones who abandoned the traditional values while others just remained there.
