I went to Stony Brook, so my experience isn't comparable to yours, but I definitely did not encounter any professors doing shit like that[0]. And to be clear, there were a few politically-minded courses in our gen-ed requirements. We had a News Literacy course that was actually really good, that I wish I could force my Facebook-brained parents to sit through.
If SBU had an indoctrination ray, they certainly had it on the wrong setting[1]. I'd already been firmly radicalized by Ron Paul revoLution warriors on Reddit into mainlining LvMI blog posts about Austrian economics and anarcho-capitalism by the end of my first year. It wasn't until I was leaving school when my political positions shifted away from that.
[0] To be clear, SBU notoriously had a heterodox economics professor who was unabashedly a Marxist. I never met him, I only heard about the professor from one of the school newspapers.
[1] Which, given everything else managed by the state of New York, would be totally on-brand for them.
