Why can't Dem's see that forcing unlikable candidates on everyone then screaming sex and racism when they don't win is a losing strategy?

Sure there were some voters who didn't not vote for Harris because of her race and gender, but they were in the minority and wouldn't have changed the outcome of the election. After Harris's loss, instead of Democrat's self reflecting about how she was a terrible candidate who ran a bad campaign, what can we do differently next time to win over voters, they doubled down on the idea she lost to sexism and racism. To independents like myself who determine election's, it's off putting when the losing party blames their loss on everyone being sexist and racist instead of admitting they lost because their candidate was unlikable and ran a terrible campaign.

Why can't Dem's see that forcing unlikable candidates on everyone then screaming sex and racism when they don't win is a losing strategy?
