Again you misinterpret, I said a big reason, not the only one. I'm also not just talking about the Trans rights part, it was also about censorhip and self-censorship. Take DEI for example, when you have a contrarian stance to the status quo (at the time) [1], you're villified and outcast. Then there is cancel culture. 1000 paper cuts and all of that, and you'd see people swaying their vote combined with Trump's rhetoric.
Also I'm not suggesting anyone has to learn anything from Trump's win, just stating the reality of what happened.

But if you believe in liberal censorship, cancel culture and DEI and critical race theory and immigrant crimes and all that other culture war/scapegoat nonsense being real then wouldn't you just be a Trump supporter? I'm saying that's all nonsense. That's why I'm saying liberals shouldn't cater to conservative delusions even if they think to be liberals, Trump will always outmatch them, he is a way more convincing bigot. Why do we need two conservative parties, it's just not a winning strategy.
