I wouldn't say it was just one thing, it was so many. The corruption of the DNC to give Hillary the nomination and her subsequent name-calling of half the country 'deplorables' was really eye-opening. Then the villain-ization of our President for no reason was tough to swallow and quite confusing. The focus the democrats have on dividing people by race, gender, ethnicity was hurtful. Trump's solution-oriented, capitalism-first approach during his first few years was really refreshing. Then the DNC forcing Pete and other 2020 candidates to fold their hand in support of Biden was disgusting to me. Biden being a decaying, senile, career-politician that would attack Trump for what Biden himself did and caused was one of the nails in the coffin. There is certainly my own growth and solidification of my beliefs, the time I spent just reading, and tbh it was hearing from black people, gay people, muslim people, etc that supported Trump and explained why was just so interesting and uplifting and real. Maybe I didn't take the red pill and it was more a slow IV infusion of a liquid red pill over years that did it.
