Arresting academics has been a red flag for societies previously. Using US history as an example, student arrests have been used in response to Vietnam protests, opposition to McCarthyism, and the civil rights movement.
History often rhymes.
At New York University, for example, several professors were arrested after encircling an encampment to try to shield student activists from police officers’ involvement.
If I were one of these students, I’d never forget this for as long as I lived. Incredible act by these professors!
You would think that past events would teach these people that they are on the wrong side of history. Its an open note test, and they're still failing.
While I agree with those professors, I've found myself mostly keeping my opinions to myself to preserve my job. You can't support allies if you're removed from the picture, and admiral or not, effective change often happens through clandestine means.
Granted, I say this as an atheist teaching at a Catholic campus. I hate religious dogma, and while I don't hide my views, I tend to t it mostly to myself (publically). The only time I'll bring up something like this is if a student needs the moral support, like someone that's having a hard time expressing doubt or wanting to be atheist. Many students need that, and I'm often the only person on campus to talk to about it.
In other words, you're better off not getting fired or arrested, living another day to continue the fight. After all, if you're caught, you can't support your cause as effectively.
