Part of it is Social Media, I know one of these people for 20+ years.
He wasn't very vocal, cuz really he had no support. Then came Social Media, started posted his shit on Facebook and before you know it, 20-30 likes and all of a sudden he had validation. and now he has gone off the charts!
funny enough , he didn't even finish high-school and majority of his friends people he hangout with are uneducated as well. Internet did amazing things, but one HUGE damage it caused? it made everyone expert of everything!
The moment someone with NO Medical education, think they are as "educated" as one because they read 1-2 Wikipedia article or watch a few YouTube videos, you created a serious problem for society!
Why do we have medical universities then? shut them down! just YouTube stuff! everyone is a Dr. !
