Lots of thinkers I'm familiar with were once on the left: Mises, Hayek, Hoppe, Williams, Sowell, the list goes on and on. What happened to them? As Dave Rubin says, they woke up.
The interview starts with him confronted by Larry Elder on systemic racism in police shootings of blacks.... He realized the myth the people accused by the left of racism was a false narrative. Of course he lost friends on the left because, as he says, you disagree with the left then your thought to be evil.
