Yes. Long trend, just undeniably obvious now.
I remember a news article about a college student at the radically left leaning university nearby. In a large lecture
room of hundreds of students the professor heard a slight questioning of the prevailing leftist slant on a topic. He pointed out the student “Well, we seem to have a right winger in the class today and a rather heavy one.” The guy was overweight and later said he was so embarrassed at the laughter and jeering from all, especially the females, that he wanted to kill himself.
I told all my kids that professors tend to be left-leaning and not to argue with them.
Imagine my surprise to find out that one professor kept complaining about the “liberal” textbook.
