If you've ever been baffled by seemingly contradictory or hypocritical rhetoric from tankies,
["Tankie" (noun) - a person with ostensibly leftist views who promotes authoritarianism and often defends dictatorships across the political spectrum; originally referred to defenders of the Soviet use of tanks to suppress protests.]
There's one thing you need to know that will clear it all up:
These people do not have, or believe in, principles or morals. The only thing they value is which of two teams you're on
This is why they rightly condemn the USA's genocide against Native Americans while ignoring, defending, or downplaying Russia's genocide of indigenous Siberians
This is why they use any Ukrainian Nazi they can find as proof that all Ukrainians are Nazis, treat any Anti-Nazi Ukrainians as inherently untrustworthy unless they start calling themselves Russian, yet make no criticisms of Russian Nazis or of the Russian government's imperialist and ethnonationalist rhetoric
This, in addition to regular antisemitism, is why they subject Jews to so many purity tests. A situation very similar to their attitude towards Ukrainians
This is why they rightly condemn the USA's prison-industrial complex but see nothing wrong with China putting Uyghurs in re-education camps
This is why they uncritically cite sources like the Grayzone while decrying any reliable publication that so much as fact-checks one of the good team's claims as a propaganda outlet for the bad team
This is why, despite rightly pointing out that no group of people is a monolith, they have the incredibly hostile reactions they have when a Palestinian criticizes Hamas, when an Iranian criticizes the Islamic Republic, when a Chinese person criticizes the CPC, or when a North Korean criticizes the Kim dynasty. Because despite what they say, they actually do consider good team countries to be monolithic - so anyone from one of those countries who criticizes their government must be a traitor working for the bad team. By contrast, anyone from a bad team country who sides with the good team must be enlightened and incapable of doing or saying anything wrong - as long as they continue to show unquestioning support for the good team
This is why their view on protesters being brutalized by their government depends entirely on which team that government is on
This is why they regard any co-operation between Palestinians and Israeli Jews as unforgiveable (see their reaction towards Standing Together). Because those Palestinian are deemed traitors who cosy up to the bad team, while the Israeli Jews are held as lying agents of the bad team who have no intention of actually working towards peace or Palestinian liberation, because why would anyone from the bad team ever support that
This is why despite an ostensible opposition to racism and other forms of ethnic bigotry, they're somewhat fond of resorting to race science when someone from a bad team country that's not their own, or a marginalized person from a bad team country that is their own, disagrees with them on a political matter
And any other apparent contradictions within their rhetoric, actions, or ideology, can also be quickly resolved if you look at what they're saying through this good team/bad team lens
This is also why the horseshoe phenomenon happens in the first place - conservatives also reject morals and principles in favor of teams, it's the basis for their entire ideology, and while some conservatives tend to view their own society as the good team, the far-right tends to claim that they are being infiltrated and/or controlled by the bad team
In both cases, Jews are considered to either be openly on the bad team, be secretly on the bad team, or possibly be on the bad team (and there's no way for them to prove their innocence)
