There’s a growing anti-intellectual strain that is growing in this country. It may be the beginning of the end of our informed democracy. In a free society, you can and should think whatever you want. If you want to think the Earth is flat, go right ahead. But if you think the Earth is flat and you have influence over others, as would successful rappers or even presidential candidates, then being wrong becomes being harmful to the health, the wealth and the security of our citizenry.
