RealDebate posted an excerpt from Folkbum today that gave me considerable clarity.
It's a neat little package. You have those who define "intellectual" making their intellectual lives quite easy. By defining those with different beliefs and opinions as "stupid", there is no need for any mental gymnastics, no need for critical thought. It's all wrapped up in a nice, neat little package called, "stupid".
After all, why go to the work of coming to a logical conclusion if you don't have to. After all, you're "intellectual".
