Even if you 100% agreed with her, the US Green Party is entirely useless. You can't win the presidency without a party, and you can't build a party by making hail Mary runs at the presidency. You have to start by squeaking out some wins in large municipalities or maybe the House, probably a blue bastion with a lazy and incompetent Dem machine. Get a Green AOC out there in the spotlight who can pull donors. Then move laterally, eating into Dem support wherever you can, and, hell, even take Republican money to undercut the Democratic party's power base. Greens don't do this - they throw all of their funding into the presidential race that they can never win. And it ought to make you think twice about supporting a party that never seems to care about winning.

As it stands, Greens functionally only exist to be a spoiler for Democrats in the presidential race. I'm not saying that them spoiling the Dems is the issue - it's that putting any faith in them to attempt their stated goals is a waste of energy.
