They should'nt come up in a philosophy or sociology class, either. During my college days, I had great professors that I'm pretty darned sure were liberal, but could not be absolutely certain about that, either. And I was never punished for speaking my opinion, which was conservative then. I also had to sit through some classes where the professors were flat out lefty loons that made no bones about that, but still was not punished for expressing my conservative opinions.
The good ones keep you in doubt and the honest ones that have even a shred of intellectual integrity will give you credit where it is due. I had a comment on a paper that read (verbatim):
"I see you have a fanatical bent for individual rights, despite the fact that we have shown this semester of how damaging they can be to the community and the individual themselves. Oh well, at least you do write well and present your point of view in a logical, concise manner, with good factual support for your conclusions and opinions."
One of the dammedest things I've ever read. I got an A on the paper, too.
Was this a class on national socialism?
