So the gist of this article is that conservatives are happier because they can see the pain, suffering, and injustice in the world and rationalize, justify, or explain away, such social and economic inequalities.

In college Psych class this behavior was classified as sociopathic.
How blissful it must be to not have a conscience or empathy.

I'd rather be ignorant than stupid. Ignorance implies a lack of knowledge which is easily correctable through education. Stupidity implies an inability to learn. Therefore; ignorance is temporary, stupidity is forever!
