Idk about this. I think most people care if their partners, sisters, daughters, and themselves can get healthcare that may involve an abortion. I think a lot of people do vote on vibes, and being "weird" is damaging. The Republicans are the party that won't stop talking about transgender people; I don't recall Harris mentioning transgendered people once.
I kinda agree with most of your other points. Economic well-being is what people vote on first and foremost. Dunno if celebrity endorsements actually hurt though. A thing to note is that, barring a tech advancement, recession, or depression, prices don't generally decrease. I.e. wages (and government assistance) needs to rise at about the same rate as inflation (preferably more than).
Harris lost because she was seen as not going to change much of anything from Biden. She even conceded to false narratives of the right (such as immigration), instead of providing an alternative narrative that could inspire people. The economic changes she ran on were uninspiring, and I'm not sure they would've helped most people (mostly people don't start small businesses, or even really have a desire to; not sure if downpayment assistance wouldn't just increased prices and fees).
I think I've heard there are a lot of genetically male, but born female people in sports. I wonder if the same people are against those people playing in sports.
Idk how many transphobic people just care about specific issues. There's a lot of "groomer" rhetoric, hate, and general disgust. It's easy to get people to hate what they don't understand; and a lot of media is trying their hardest to cultivate hate against trans people to create an out-group, so they can control the in-group.
