Depends?
I rarely if ever heard any political opinion debate in my physics, chemistry or math classes.
We were too busy learning real science and applied math LOL.
But , other social science and liberal arts classes have a left leaning tilt.
Too many elite level intellectuals never served in the military or faced thugs in the hood.
They have a sheltered life experience and look at society in idealistic, esoteric terms.
My wife is friends with a younger woman who's a CPA from Chicago.
Her gun control views changed after an armed thug broke in and robbed her.
She now has a concealed carry permit and a 45 caliber snub nose.
Same here. The closest I ever came to hearing politics discussed in class was a statistics professor talking about pooled and unpooled variance testing by using polls published by newspapers.
I work at a University. I see so many people talk about how we brainwash kids or turn them into Marxists. Mostly from people who haven't stepped foot in a University classroom. Here's the reality, based on the classes I teach:
I get to spend an awful lot of time talking about math and computer science, while most of your kids sit and play games or talk to their friends on their phones or laptops, while sipping Monster Energy or Starbucks lattes.
And then, around final time I get to spend an awful lot of time hearing your kids ask me how they really need a B to keep their financial aid, or how they need only this one class to graduate, and how they know the material but don't test well because they have a "testing disability".
Trust me, even if University professors talked about politics non-stop, Junior would too busy doing nothing to actually pay any attention.
That's not to say that there aren't liberals in Universities. There are, usually concentrated in the departments where the dumbest of the dumb kids go for an easy degree. And some are more vocal than others. But how's that different than any other workplace?
And there you have it, a glimpse in the life of someone in academia.
