Hmm for me a pretty recent 180 i took was on Deng Xiaoping. I was a commie but I really wasn't super educated on the state of AES(even though i am part of the chinese diaspora) and was always under the impression that it was capitalism. That deng xiaoping turned china capitalist. Probably not really as big of an 180 as some other people here but really learning about china was really inspiring and restored my hope in the world ig. I feel way more patriotic towards china right than amerikkka.
Unfortunately no time to do so, but maybe in the future.
