discriminating in employment due to one's affiliation is illegal in state and federal employment [1]. That does not mean one can break ToS and for example, publish on a massive public platform, your private opinion (which can be misconstrued as your employer's). Most employers have ToS against online activity during employment, for that reason.

It is also illegal to do the same for students. [2]

Faculty is already protected under tenure rules. And even for the nontenured, who really needs protecting ? Only 5.7% of all faculty are registered as conservative as of 2020 [3]

My point remains. "Filtering out" is illegal. Setting the stage on what is american, is not.

Plenty of right wingers are granted visas to spread nonsense in America. It would make sense to put them on visa bans.

> next time the Democrats get elected they will filter out all the right wing professors/students, and this will make you happy

Yes, actually. We have the precedent. Both for the action and for these people being dangerous to our safety and civil society.
