Sometimes it just happens on its own over time.
I remember getting out of college pretty liberal and borderline full SJW. But when you enter the real world and see how people really are, you start to gain a different perspective. I started to notice how my college friends really hated men, how they never seemed to really grow up, how they all started making up new genders for themselves out of nowhere.
Then the 2016 election happened and everything exploded like a goddamn nuke. Everyone went rabid, foaming at the mouth, wailing, saying the stupidest goddamn shit imaginable and refusing to see in shades of gray.
It was a sober wakeup call and was enough to throw a left-leaning person like me in the complete opposite direction. I think there are plenty of other people out there. Hopefully, more and more people will get fed up with it all and change the same way.
