For those who like to listen to Sam Vaknin, watching the documentary on him, I, Psychopath, is useful. It is 84 minutes in total.
This morning I watched a wonderful video created by Beau of the Fifth Column about MEGA hats, the new harassment free app for those who wear them, and what all who wear those hats could learn about micro-aggression, hate, and making others feel like shit.
Here Dr. Howard Wetsman talks about how making people feel less than others lowers dopamine tone and causes mental health issues. His perspective is on addiction. I think treating others as less than causes many of of our health issues.
