As someone who got a BA in history before moving on to get 2 grad degrees in more useful subjects, I’m very familiar with this.
For most liberal arts degrees there are only 2 paths. Either you teach or you go to law school which has become ever less attractive over the last 30 years.....too expensive, and too many lawyers meaning earning potential for many is lousy. So the liberal arts degree is just not very practical - and no, I wouldn’t major in that if I had it to do all over again.
The second issue is not just PC but the ideological Stalinism of the PCers. History is just current events far enough back in time that we call it history. There is no capital “T” Platonic Truth in how to interpret it. People are going to disagree just as much as they disagree about current politics. That’s all well and good so long as they can defend their opinions with facts, quotes, sources etc. a good history education would encompass learning about the same event from 2 very different perspectives. The student could take that in, do their own reading and decide where they think reality lies.
That is not how history is taught today. PC Revisionists came to really dominate Academia from the 70s-90s. Buck them......disagree with their dogma in a paper or thesis or be a grad student for a non Leftist prof, and you can forget about getting tenure or even getting hired at most universities. Academics then try to push THEIR Revisionist narrative as though it were the only way to view historical events and they immediately seek to demean anybody who disagrees. Even the work of earlier historians who were university profs now somehow doesn’t count. Needless to say, anything said by anybody outside the Academy - which they now dominate is automatically invalid. Inconvenient historical facts and quotes - even if indisputable and backed up by impeccable sources - can be dismissed.
Their goal is not to educate. It is to indoctrinate. Fortunately much of the public sees it and refuses to buy their BS - to their eternal frustration.
Blame Howard Zinn and Matt Damon for accelerating and mainstreaming this. Most schools are just extensions of one: The Frankfurt School. (I emphatically include seminaries.)
My former best friend majored in History before attending a Southern Baptist seminary. He became a thorough Cultural Marxist though he would not have accepted the label.
He was one of the most ignorant persons I knew about Western history generally, and American history specifically. He hated anything that portrayed America in a positive light, and loved anything that portrayed it in a negative light.
I began to worry about him - after our shared private Christian prep school years - when I saw how much he thrived and loved being in a communist indoctrination center (public college, then public university).
I tried to maintain a relationship with him for about twenty years. We are no longer friends.
