Here is a commercial world version of what this is about:
A company is started up to build cars. Someone applies to get a job with that company.
After joining the staff, they decide that they don't think cars are a good idea.
The car manufacturer tells them "If you are opposed to the idea of cars, get a job somewhere else. We are here to build cars."
I'd side with the car company, myself.
equating education with selling cars...

You are also ignoring the facts to suit your politics.
Unless the professors were working to prevent ANYONE ANYWHERE from teaching a class that did not fit their ideas, there was no suppression, and no need to "show all sides of the subject."
Since you apparently don't think logic applies to the working world, how about a school-based analogy?
If someone is teaching a course on how to best arm the military, should students taking that class be allowed to spend the bulk of the class time arguing that war is wrong, and that no weapons should be allowed anywhere? Just to make sure of "showing all sides"? I would say logically, no.
But apparently you would differ.
yes, i would... learning comes from within, not just because someone says so... the more they engage each other, the more they want to learn the truth...i know liberals are fine with "because i said so" type teaching, but it's not a teaching technique that is in use, till now... sounds more like hitlers school for the blind...
