They're the equivalent of MAGA.

MAGA hates democrats, leftists, liberals, and minorities and that drives their every thought and action. Trump can do no wrong even as modern day Hitler.

Tankies hate the west and that drives their every thought and action. Russia and China can do no wrong because they're against the west.

Both are authoritarian and wish to imprison or even execute their enemies (literally threatening to eliminate an entire civilization while funding the genocide of another), eliminate speech they disagree with (NSPM-7), spread blatant propaganda constantly in an attempt to instill bias (similar to how Detroit just voted for Stevens after a deluge of Israel money funding attack ad after attack ad on every media source), and create indoctrination camps like the brown and red shirts to instill their preferred values in the upcoming generations (dismantling higher education, attempting to start their own "non-woke" universities).

Authoritarianism is the problem. We should be uncompromising in protecting all peoples. Whoever seeks to crush others is the enemy. The only thing intolerable are those who's ideologies are rooted in intolerance. Socialism is anodyne to authoritarianism as it seeks to unite all peoples and distribute power amongst all members of society. The exact opposite of authoritarianism seeking to consolidate power in the few.
