OK, so now we know how you voted. What fraction of the electorate are you?
> The problem wasn't really Harris, who got very close to half the vote.
Which in this case is called "losing." Trump even won the popular vote that time.
> The problem is that half the voting population does not think that electing a fascist demagogue is that big of a deal, or compares favorably to electing a boring centrist.
IMHO, one of the Democrats' many fuck-ups was they overdid the "fascist demagogue" line of attack, basically neutering it.
It's pretty clear roughly what your political views are, but let me hazard a guess that you're far away from being a swing voter. IMHO, another one of the Democrats' fuck-ups was being unwilling to make their most loyal voters uncomfortable, and instead demanding that persuadable voters tolerate discomfort, which is a tough sell.
> This suggests that our civic culture is fundamentally broken at the moment. You can't run a society like this!
How very convenient! Doesn't that mean you don't have to adapt in any way that's uncomfortable to you?
