Why do Democrat voters hate Tulsi so much?

What the title said. I don’t understand the hatred for her. People accused her of being a Russian asset, said that she would never drop out of the race, she would accept a job for Fox News, and would run 3rd party or endorse Trump, but none of these things happened. After it became clear that Biden was going to win, she quickly endorsed him. It seems to me like a ton of people just bought into the nonsense smears mentioned above, and have refused to let go of their views on her out of stubbornness.

She goes on Tucker Carlson a lot.

How is that a bad thing tho? By going on Tucker Carlson, she makes sure that his viewers aren’t just listening to a bunch of nonsensical Trumpists all the time

She became an conservative ideologue on foreign policy, while she remains a Democrat, like appeasing Assad and agreeing with Fox news

She went after both Harris and Warren in Dem debate, that's why

Since when did being anti-war become a conservative stance?
