For me it was in high school. I was a typical indoctrinated lefty soy-cuck at the time. I know, I know. Anyways...
So this girl I was friends with and had a crush on, she got it in her head one day that she wanted to be a guy. Normally I would have just rolled with it, but since I liked her my ape brain refused to make that kind of concession. I just saw her as a girl no matter what. I asked her why I should call her a “he” and got the usual spiel you get, you know the one. Blah blah common decency, blah blah. At the time it worked, I felt guilty and tried to go along with it.
Some time later, she really upset me. I don’t recall why now, but I said to her, I said “What you said the other day really hurt my feelings.”
She said, “I don’t care.”
That’s when it hit me. These people never cared about being good to each other and getting along. They only want compliance. After that I started seeing it everywhere, and getting more and more disgusted. With that jenga block pulled out, the whole tower collapsed.
And that’s how I became the dangerous alt-right deplorable that I am today. Thank you for coming to my ted talk.
I had numerous steps to being completely redpilled.
1st redpill: Being falsely accused of having "taken advantage" of a girl back in high school. She literally approached me, but somehow I got blamed for her sexual behavior and was treated like the scum of the Earth for months because there was a two years age difference between us. Yes God forbid a 17 year old be attracted to a 15 year old girl. The main person who started the campaign towards getting everybody to hate me was a stereotypical SJW type girl.
After that I went on a really extreme alt right path. Then I became a moderate liberal for a couple years because my freshman roommate was a massive asshole and he just happened to be Republican (not a very smart or coherent one though) so I think he turned me off of Republicanism for a little while.
After that, I'd say a long series of small redpills was what turned me right-wing. After I got accused of taking advantage of that girl, about a half a dozen of my friends got falsely accused of sexual assault or harassment as well. I also went to a lot of raves and music festivals and saw how extreme and dangerous people's drug use can really get and was disturbed by it.
At college parties, started realizing that every time I made out with a girl and she wanted nothing to do with me afterward and just wanted it to be a one time thing that it made me feel like shit. That I'd say really redpilled me on promiscuity and made me realize there's literally no point to promiscuity. Its not even fun or pleasurable. It actually really fucking sucks. We're just told that it should be fun when there's nothing special about it at all. I'm not a prude, I am extremely hedonistic, but there's literally no fun to be had in promiscuity. You can have just as much if not more fun with one girl than ten. Promiscuity does nothing but hurt you.
The next thing I noticed was that girls raised in patriarchal environments/societies are a lot nicer than girls raised with leftist values. The religious girls were much nicer to me. The foreign exchange students from Asian countries were much nicer to me. Girls raised with leftist values always seem to be brimming with hostility and suspicion towards you and it was incredible how much of a difference it made to talk to somebody and not feel that hostility and suspicion.
The last thing though that really sealed the deal for me was seeing how the media treated Nick Sandmann. That's when I completely lost respect for the Democrats and realized there were no moral lows they weren't willing to stoop to in order to win. They would destroy a completely innocent 15 year old's life just to suit their agenda. I was profoundly disturbed by it and decided that the mainstream media really was the enemy of the people.
