I so agree. I am slightly younger than Horowitz, and remember his writing when he was the editor for Ramparts magazine. I was on a campus infested with leftists at the time. I too, was a lefty for a while, that is, until I got a job in the private sector. (Unlike Bill Clinton).
My take is that the outrageous Leftist propaganda effort going on in education is self defeating. For instance, it was the college kids in the 1980s who first coined the words, “Politically Correct” to describe what was going down on campus.
After all, kids tend to rebel against authority figures, so if the college authorities are saying “socialism is good” - the kids go in the opposite direction.

Politics of the family more important than those from Leftist education.
