Sure, there’s a process involved and as we’re at the early stages now, things like this will happen, at least until we get to the teacher-less classes. But still, look at the difference between that experience and being in the class, live, where not only do you have to give back the right answer, but you can’t even mutter any dissent under your breath.
For example, in the experience you just cited, yeah, you had to give back the answer the leftist instructor expected, but minutes later you got to vent your disgust over this with like minded students. And as an act of defiance you could still take the course wearing a MAGA hat (and maybe nothing else) while you take the class, and the teacher would never know. So those are brainwashing cures you can’t really get in the traditional university experience.
Students in an online course are NOT able to complain to other students in the same course about a professor’s indoctrination efforts. Their only contact with other students in the course is through the online monitored group conversations. A conservative student is going to be VERY reluctant to share his disagreements about the prof’s view if he thinks that it could affect his grade. Maybe your experience is different from mine, but that is the environment that I have seen in online courses.
