I don’t think that’s a very charitable interpretation of what is easily explained by honest political differences. People can and do work together when possible, but there are also issues too important to compromise on.
She wants to play them off as honest political differences anyway.
When her actions match her supposed intentions then I’d be more willing to give her charity.
You’re painting “so many leftists we see on the net” with that same brush though. Is it so hard to believe that there are people genuinely to the left of you politically? What “actions” do you need to see from Jill Stein? She’s been running for office, giving interviews and speeches that platform issues that the dems are weak on. If nothing else she’s forcing democrats like AOC (and you, presumably) to engage with these ideas or risk political consequences. If we didn’t have 3rd party candidates to the left, there would be even less pressure on the dems to adopt leftist policies.
She could start by dropping out of the race, endorsing Kamala, and then putting every dollar she has into organizing for national ranked choice voting so that hopefully once in my life I can vote my conscience at the same time I vote pragmatically.
I sincerely doubt there is much room between where Stein is at on the issues and where AOC is at on the issues - the main difference is that AOC is not running for president and making it easier for despicable people who don’t care about anything to win.
