Maybe, people also didn't want a neolib candidate who had no populist appeal. She didn't acknowledge legitimate grievances of the voters. The Democrat party should've held primaries, but they just put Harris in at the end. There's many factors beyond sexism.
Honestly, karma is just for getting started on reddit. Certain subreddits, require your account to exist and have a certain amount of karma to "validate" it. I don't think people care about getting karma beyond that point.
