I agree with you, but I was referring to unmarketable parts as much as the politicalized parts. You would be shocked how worthless a physics degree is without a graduate degree for example. That was true for a biology degree long before the left decided to excise politically inconvenient parts of that field. It's mostly engineering, programming, and the more applied parts of math and statistics that are still useful. Even then you have to be careful that you don't end up in the subfield that gets outsourced to India.
