[notconservative]

I can say from first hand experience that this has happened. I know several closeted conservatives at my workplace and we all know that you shouldn't share your political leanings with anyone. Luckily there is some internal diversity of opinions. So, we can confront each other without consequences on things like immigration, labor issues, free trade, and social programs.

But, there are naturally areas where we all agree: guns, some other economic stuff, etc. So those opinions go completely unchallenged, where it'd be healthier to have liberal people to test those opinions.
