Literally this happened to me in 2004. Are you me?! I was fired from a bookstore after getting into MRA and making a very insensitive topic. Money turned up missing in the safe and everybody suspected me because I was an arrogant asshole back then. I did not steal, but looking back I understand why they might have suspected me.
I was so ignorant then and was also trying to find out who I was. Anything contrarian attracted me. Most of the kids in my school were Liberal and Democrats so I became extreme libertarian and an MRA. The more and more I read history and about everything in the world, my world view expanded and my world view slowly started changing and I realized how wrong I had been.
Your story sounds a lot like mine. You sound like me.
