I want to draw attention to the elephant in the room.
Leading up to the election, and perhaps even more prominently now, we've been seeing droves of people on the internet displaying a series of traits in common.
- Claiming to be leftists
- Dedicating most of their posting to dismantling any power possessed by the left
- Encouraging leftists not to vote or to vote for third party candidates
- Highlighting issues with the Democratic party as being disqualifying while ignoring the objectively worse positions held by the Republican party
- Attacking anyone who promotes defending leftist political power by claiming they are centrists and that the attacker is "to the left of them"
- Using US foreign policy as a moral cudgel to disempower any attempt at legitimate engagement with the US political system
- Seemingly doing nothing to actually mount resistance against authoritarianism
When you look at an aerial view of these behaviors in conjunction with one another, what they're accomplishing is pretty plain to see, in my opinion. It's a way of utilizing the moral scrupulousness of the left to cut our teeth out politically. We get so caught up in giving these arguments the benefit of the doubt and of making sure people who claim to be leftists have a platform that we're missing ideological parasites in our midst.
This is not a good-faith discourse. This is not friendly disagreement. This is, largely, not even internal disagreement. It is infiltration, and it's extremely effective.
Before attacking this argument as lacking proof, just do a little thought experiment with me. If there is a vector that allows authoritarians to dismantle all progress made by the left, to demotivate us and to detract from our ability to form coalitions and build solidarity, do you really think they wouldn't take advantage of it?
By refusing to ever question those who do nothing with their time in our spaces but try to drive a wedge between us, to take away our power and make us feel helpless and hopeless, we're giving them exactly that vector. I am telling you, they are using it.
We need to stop letting them. We need to see it for what it is, get the word out, and remember, as the political left, how to use the tools that we have to change society. It starts with us between one another. It starts with what we do in the spaces that we inhabit. They know this, and it's why they're targeting us here.
Stop being an easy target. Stop feeding the cuckoo.

The current US voting system does not allow for a 3rd party to have a chance. If you want a new party, then you either need to replace one of the main two, or change the electoral rules.
From the outside, it doesn't seem like either option is likely to happen peacefully, so things will likely need to get way much worse before they get any better.
Oh, I know. But imagine, if you will, if enough people collectively decided to vote 3rd party. It's a minority of Americans who even vote at all. If a third party received the majority of votes, they would have to be put in office -- hypothetically at least.
Then it would either become the 1st/2nd party, or disappear into oblivion. If itvciukd became part of Congress, where it could look for alliances be... but based on current sentiment, it seems unlikely.
