RE: Intellectuals are the dumbest people in society (no, really)
Intelligence is such an overrated concept. Having a high IQ doesn't mean much if you are completely detached from reality.
Funny that you would put someone with an atheist t-shirt; these people are usually the worst offenders. Most of those I've (most likely) correctly see that God doesn't exist. But sadly, they now devote this former religious fervor to government. And they completely refuse facts going against their socialism worship.
Finally, intelligence goes way beyond IQ. Despite "only" having high school education and a nursing class (not sure about the exact training), my mother made a very honorable living and is now retired. My younger brother - my polar opposite - found his way about much wandering, pressured to go to college and such. In the end, he took a class in restauration and seems to be happy.
In this manner, intelligence is knowing how to put your talents to their best use, even if it means not being a PhD in one-legged, one-eyed, blue-haired feminist LatinX studies
