Accelerationism means supporting the most competent capitalists and imperialists, to speed up concentration of capital and speed up collapse as a consequence. The Democrats are the more competent party when it comes to ensuring capitalism remains more stable. This would make them the accelerationist option. Accelerationism isn't "burn down the system now," it's a specific (and wrong) strategy.

As for claiming "all leftist thought is tankie-owned," I did no such thing. I generally categorize the left as being predominantly Marxists and anarchists, those who oppose capitalism. I myself am a Marxist-Leninist, which is an ideology that has consistently managed to both take power for the working class, and wield it to do tremendous things like double life expectancies, eradicate homelessness, and more. Not sure what you mean by your assertion that I am painting myself into an ineffective corner, nor the bit on saying "clear all."

Marxist-Leninist strategy is time-tested and clear-cut. Capitalism runs into crisis from its own contradictions, so to make revolution we need to develop a working class party that builds up disciplined, educated cadre that struggle along with the rest of the working class directly against the system. With this party, we can make effective organizers, educate the working class, agitate among them against the capitalist system itself, and create unity among the working class that can become an unbreakable hammer, an unblockable spear. The party just becomes the spearhead, the actual working class is the one making the real moves and changes. You know, the old adage,

Educate

Agitate

Organize!
