There was that unexplained Kremlin dinner. She spouted the Anti-Hillary propaganda that Russia was using verbatim. She was also anti-science and a diet racist. Russia loves to prop up racist, anti-intellectual candidates. Her challenging the election results in some states seemed to have no benefit to her other than sowing distrust in our democracy. Her actions were very suspicious.Actually, he is right, this has been a major complaint Democrats had with 3rd parties since Al Gore lost. Most of the posts during the elections that Jill Stein was mentioned in were shitting on her mainly due to her running and shitting on her supporters for voting her.
You can speak for yourself, but that is what I seen of most post regarding her during the election, that and her bits of anti-science beliefs (wifi signals, anti-vaxxors like you mentioned, etc.)
