They do it because they are educated. By definition, it cannot be a dumb pipe. The very process of education creates a perspective that is logical, balanced, and informed. An educated person understands that climate change is real, that CO2 warms the planet, how could they not? It is physics. They know that sex is informed by both the body and the brain, how could they not? That is physiology. They know that skin color is arbitrary. They read books, and they work with other cultures and races. A professor of Economics cannot teach trickle down, it's based in nonsense and simply untrue. No more than would a professor of Medicine teach you that someone can be told what sex to be. They don't mean to be elite in the same way that the rich don't mean to be rich: They just are. If you are truly educated, you would likely hold the same values that they do, because you've been exposed to the same set of clear and verified facts. I cannot understand this insistence that someone's faith or ignorance should be held with equal regard to my facts. Ignorance is they cause of most of the evils of this world, I do not confuse wrong from right, nor do I confuse educated from ignorant.
