Unity with tankies should be rejected just as readily as unity with fascists
Any attempt at comradeship with a tankie is doomed to fail. Regardless of what they claim, tankies aren't interested in any form of debate, compromise, or exchange of ideas with anarchists or communists. Their only goal is to give their dangerous ideology an appearance of legitimacy. To wrongly represent it as a legit form of communism so they may further pollute radical politics with their tyrannical capitalist cult.
Anarchy is pure anathema to the tankie. We espouse opposition to authoritarianism, hierarchy, bureaucracy, state-sanctioned violence, prisons, worker exploitation, ecosystem destruction, state-capitalism and imperialism. This makes us, to the tankie, "reactionary counter-revolutionary imperialist scum". Doublespeak like this is one of their defining traits.
Behind closed doors, they see us as a threat to their plans for strongman dictatorships, cults of personality, mega-industrial capitalism and gulags as far as the eye can see. We are vermin to the tankie; fit only to be ridiculed and then swiftly exterminated once they seize power. Anarchy is their absolute worst fear. Anarchists are the biggest threat to their plans for party dictatorship.
They latch onto our movements and gradually corrupt them with their reactionary rhetoric and divide-and-conquer tactics. Their goals aren't even slightly aligned with ours, but they use shame and cries of victimization to squirrel themselves into our spaces. Their demands for 'left unity' and an end to 'divisiveness' are obvious wolves in sheep's clothing and should be rejected outright.
We can't lose sight of the historical fact that genocide, nationalism, capitalism, bigotry, imperialism, struggle sessions and mass incarceration are some of the central tenets of ML(M) practice, and whether they admit it publicly or not, something all tankies believe is necessary to ensure their vanguard's dictatorship and cement their own power on the hierarchy.
Their only purpose in engaging you is to normalize their toxic beliefs and make us accepting of their presence in radical groups so they can grow their ranks.
If you welcome tankies into your spaces, if you engage tankies in civil discourse, if you entertain their repugnant ideas or buy into their absurd notions of 'left unity' and enable their attempts to create divisions between anarchists and sow discord, then they have already succeeded in poisoning your movement and rendering it useless.
