Step1: For me I distinctly remember a moment in like 10th grade where I said, oh that guy is an idiot and agrees with me. It was the first moment I called into question my political beliefs as a liberal.

Step 2: Was asking questions about obvious hypocrisy over a few years. Namely stuff like why girls get math help when boys don't get writing help. This was important to me as I was still ashamed that I was bad at spelling. But all I ever saw was token lip service and uncomfortable answers.

Step 3: Gamergate. Where people I had agreed with politically had decided that the hypocrisy was exactly what they wanted. And I suddenly rejected the foundation of ideas they had.

Step 4: Trump's election. I called it like a year in advance. Not that I was happy about it. But I recognized the undercurrent that gamergate was with Trump. Where everyone that felt marginalized by the approved hypocrisy was left smolderingly angry. And that Hillary had alienated the Bernie supporters without even attempting to build community support. Now I see TDS, as a comicbook youtube suggested, as brain-damage. Because it proved the world did not run off what the propaganda says and that the foundation of their worldview was flawed. And the stress and fear from that made them double down on it.

So here I am now. A classical liberal that sees a complete lack of either party attempting to promote liberty.
