My parents have been religiously listening to the likes of Rush Limbaugh since the early 90's on a daily basis. I recall listening to it on our drive into work together.

30+ years of hearing whatever the tv/radio host du jour says, without critical thinking, taking it at face value, 8+ hours every day. In the car to work, radio on while working, drive home, and then turn the TV on till bed time.

Then take a drive through rural America and see that education isn't an important pillar.

I went to college (neither of my parents did) and made it out with a different perspective, but my brother did not. He peddles in conspiracy theories and doesn't believe humans landed on the moon. My father regrets sending me to college.
