When right-wing people see the statistics that educated people are more likely to be left-wing, they apply the obvious incorrect logic that 'education is indoctrinating our children'.

The simple fact of the matter is, that in high school, college, and university, I was exposed to people. I played sports with people from every culture, shared classrooms and completed group projects with them. I was taught by people with different cultural backgrounds and I can promise, not a single word of it had anything to do with politics.

Meanwhile, the uneducated are born in their small town, they go to work in their small town, they are surrounded by the same people they went to high school with (presumably from their own cultural background) and ultimately, they listen to mass-media telling them that X people are bad.

And if you explain this to them, they'll still say that you're brainwashed.
