The answer is that Jill Stein is almost none of the things that people are accusing her to be in this thread. She didn’t tell anyone to vote for Trump over democrats. She isn’t Putin’s puppet or a Russian spy just because she had dinner at the same table as Putin once. She never was anti-vax (i think she said people should be allowed the freedom to choose for themselves). She isn’t a spoiler candidate and voting for her isn’t a vote for trump.
All this shit is propaganda that’s worked very well on democrats in the US.
I think you are right. I wanted to add that often times people will have a strong sense of justice or revenge and want to see something bad happen to a person who did bad things.
Other times when people call for someone’s death, it’s because they don’t believe that there is any other way to stop the harm that person is causing. This tends to be the case when political figures start violating the civil and human rights of their constituents.
