No, I draw it from decades of living life and reading the news.
I remember my college days, when the loony left ran the politics of the place, because normal people were uninterested, beyond having a good laugh at their right-on craziness, that achieved precisely nothing.
Now social media puts their immature views front and center in our politics and their opinions are dragged ever further to the crazy left by professors who are not interested in being - or are even paid to be - unbiased in their teaching.
