It was Charlottesville for me. I wasn't a leftoid before; just kind of apolitical and didn't take much of a side. Which is a condition that could have led to becoming NPC-lite several years later if left unchecked.

Saw so many friends having a meltdown about orange man supposedly praising Nazis and I thought that I finally had the smoking gun that would let me agree with all the people around me parroting that he was a white supremacist (I was in university at the time). Watched the speech for myself and was absolutely floored at the difference between the reality versus what was being reported and discussed.
