1. She falsely claimed to be Native American
2. She tried to Snake Bernie with that bullshyt Sexist story.
3. she refused to endorse her friend and fellow progressive in 2016
4. She refused to endorse her friend and fellow progressive in 2020
5. Lies about her political awareness when she was a Republican up until the age of 46.
6. Hides behind her gender.
These are serious character flaws regardless of her political positions which I happen to agree with most of the time.
The first point is the only one that holds any weight.
The second point is believable given Bernie's history of being pretty ignorant and cold. He's proudly stated the following:
1) aren't all drug dealers African American to attempt to explain away police interaction with black youth (he said this in the face of a black activist)
2) white people aren't racist for feeling uncomfortable about voting for a black man
3) white MS residents aren't racists for not voting for Obama, he just didn't do a good enough job courting them.
Three and four, she was right to put actual action above one man.
Five, she's been open about her past. The Intercept has a story with her on that history, and it isn't as simple as you're presenting.

Six is just bullshyt. What does it mean to "hide behind your gender"? You give away the game when you use phrases like that.
