Democrats aren't attacking Jill Stein because they think she is taking votes from Kamala Harris. No one I know who's voting Green would consider a vote for Harris at this point. They're attacking Jill Stein because they don't want voters to know that there can be a worker-centered party to the left of the Democrats that supports popular policies like Medicare for All, a $25 wage and federally guaranteed housing.
There are 80+ million eligible voters who don't vote at all because they don't see the point. Democrats are okay with this, in fact, they don't want any candidate to their left to appeal to those voters with popular policies.
The fact that the Green Party exists shows that the Democrats aren't pushing the most progressive policies. Jill Stein's candidacy shows that it's possible to support reproductive justice AND be against funding and arming a genocide. That we can end homelessness if we stopped funding endless wars around the globe.
Democrats don't want anyone to the left of them to exist because it's the only way they can convince Americans that Dem policies are "the best that we can do". To Dems, anything else is just "asking for a pony".
Don't fall for it. Despite Dem's desire to have you think otherwise, things don't have to be this way.
Another world is possible.
We've got a very serious person over here
Yes what's serious is definitely putting your faith in a system with two options and if you don't vote for the one then the other one wins and the system is destroyed (half the population doesn't vote, the half that does votes for the destruction option). Sometimes even if you vote for the one the other gets to win because we don't really care about votes. BTW we've been doing this song and dance about "keeping [villain of the week] out of the white house!" since the 70's. Ask yourself this: If Trump truly was a threat to democracy, why have the dems done absolutely fuck all? Why are they completely unwilling to budge on any of their far-right genocidal policies? If Trump is truly this existential threat, why has he been allowed to exist for four years? Why did they try to run Biden, a man with obvious dementia, if Trump was truly this unique evil that will tear America apart? Doesn't seem like the dems are very serious.
What's super duper serious is going to argue with people who won't vote for genocide that they should vote for genocide. The most serious people in the room do this thing where they for some reason decide to focus on third party voters (who these serious people also say is of such an insignificant size that they do not matter at all) instead of going outside and knocking on doors talking to the more than 50% that doesn't vote
Online arguments are totally the sign of being a Serious Person (TM)
