I used to be a hardcore Bernie Bro too. I canvassed for him here in CA and even went to canvass for him in Phoenix for a couple of days before the Arizona primaries. However, I grew disenchanted with him and the left in general. It first started when I got to see how radical and full of hatred the left was becoming. Initially, when I was volunteering with Bernie in Phoenix, most of my fellow volunteers were great people. We didn't care whether you were Republican or Democrat. We believed that while there were some evil people out there, most just had different views on how to make America better. When I was volunteering for Bernie in CA, I mentioned to my fellow volunteers about the mass rape that Muslim migrants were committing in Europe (i.e. Sweden & Colonge, Germany). To my surprise, no-one seemed interested. This was one of the things that made me walk away. When many on the left hear of crimes committed by minorities, they have no interest, no matter how horrible the crime was. It was as if minorities should be allowed to get away with crimes, even those as horrible as rape. When I was accepted to serve as a one-day student lobbyist in Sacramento in college, one of the speakers who spoke to the students told everyone that America was a racist country in which African-Americans were suppressed. But he only gave examples of discrimination before the civil rights era and even told the audience that he wanted to protect young African-Americans from "white ideologies." I guess he didn't quite like representative democracy, constitutionalism, and separation of powers. Despite his comments, almost everyone in the room clapped. When I mentioned that we should try to bridge gaps between campus clubs of various political persuasions. I was snubbed. Beforehand, I had thought that we on the left were the "good side." However, my time at the university along with news I saw coming from other campuses, proved me wrong. I then began to see news and youtube vids that introduced me to right's perspective. All of this helped me shift more and more towards the right. I know many on here don't like Ben Shapiro, but he was vital in helping me make that shift. John Stossel videos on youtube also helped me and my parents lose confidence in leftist economics. If you want to redpill your son, John Stossel, Larry Elder, and Thomas Sowell vids might help. Dave Rubin's first interview with Larry Elder may redpill your son like it red pilled Dave haha. Sorry for the long post. I hope your are able to convert your fam!
