Sorry you "gloated" at the non-sophistication of conservatives, faithfully voted Democrat and were "trained" (I think you are implying indoctrinated) to think one way.
So now you are better than to think you are better than others? Rather than having an earlier disdainful view of conservatives, do you now have a disdain of liberals who don't understand "common sense"?
When people invoke common sense, what higher source of understanding is that? In a world of science and reasoning, do we say, "here is what I believe and common sense proves it"? 
Sure, not walking in front of a truck is common sense. Which side is common sense on in regards to the Afghanistan war? 
Ascribing the correctness of one's view because it's common sense offers no option to question the assertion. How is that being open to criticism? Can you imagine writing a thesis with a defense that it is "common sense"? 
Common sense is a logical fallacy: https://yandoo.wordpress.com/2014/12/28/common-sense-fallacy/
