I don't know if I was ever "radicalized", but I was beat up ( a few times) by cops and witnessed non-violent priests and nuns beat-up, stripped and humiliated by police during peaceful protests with Operation Rescue at the abortion clinics in the late 80's and early 90's. I realized then that the police and "most people" in authority will commit violence, subtrifuge and detraction against another if they know they will not get caught. We did not have the courts or the press on our side so nothing was ever done in our defense.
I knew the corruption was deep at that point. After one rescue , upon returning home after a short incarceration, I literally trembled when I saw a cop car or heard a police siren. it only lasted a few days, but at that point it was very easy for me to believe the pervasive underlying evil that was lying just below the surface of our false society that hated Christ. I never fell for the Iraq wars, Jews, Israel, vaccines and 9/11 after what I experienced.
I was always the consumate "conspiracy theorist" and remain so. Usually it pans out in the end.
