>Unfireable save for clear violations of policies such as sexual harassment
I would take a look at (and consider donating to) FIRE to understand the current state of academic freedom in universities.

Just to give two examples:
Bret Weinstein was fired from Evergreen for not participating in a no-white-people-on-campus day (and he was also subject to credible death threats, requiring police escorts when present on campus)
Gordon Klein was suspended for refusing to promise to give higher grades to black students. https://nypost.com/2020/06/10/ucla-suspends-professor-for-re...
And then we have the epidemic of academic mobbing, where colleagues engage in herding behavior that focus their rage on one of their colleagues in a type of modern equivalent of Monsters on Maple Street. It is estimated that 12 percent of those mobbed end up committing suicide. https://www.universityaffairs.ca/opinion/in-my-opinion/acade...
There are many, many things that will get you fired or subject to attack in the modern university, and I don't see any reason to view academia as a place that provides more intellectual freedom than private industry. Indeed, it is often the epicenter of cancel culture and petty utopian dictators.
