I don't disagree with your list of their actions - but you are ascribing an erroneous motive, based on some kind of 4d chess argument that the ADL are actually "antisemitic", to obfuscate the far simpler reality - the ADL deliberately props up black, Islam, & leftist extremist groups because they view them as an enemy of white people. Absolutely everything you described is very simply explained by a blind, raging, rabid I dare say, hatred of white people & white self determination groups to the point where they're even willing to look the other way when one of these groups attacks their own.
They hate white groups so much that they focus all their efforts into attacking them - to the absurd point where these groups are largely comprised of their own people. They viciously target any member of a white group for unrelated crimes because they're absolutely desperate to paint these white groups as bad guys.
All the ADL talks about is "antisemitism". It's all they have ever talked about, from their founding up until today. But in reality as you have deduced, their true motivation is hating, killing, and persecuting white people. You even parrot their frame of reference - these are not "white supremacist" groups, these are groups of people who desire that their own government represents their interests over the interests of foreigners, and that they as a people have a fundamental right to exist and the right to self determination. This is really what the ADL hates most.
I don't think these are mutually exclusive. The ADL hates white people and serves the neoliberal agenda of ethnocosmopolitism, but their race politics against whites are just one facet of that greater neoliberal poltical agenda rather than their core identity, and running support for antisemitism has been another facet. They are happy to smear
any group that would run afoul of their political alliance. Not just white people. They'll target black men for running off the plantation, like Enrique Tarrio. Overlooking that proud boys take an explicit vow to oppose anti-semitism, and are largely supportive of a pro-jewish agenda, while the ADL gets in bed with October 7th cheerleaders.
Its very obvious from the reference frame of regulatory capture. Groups like the ADL and SPLC and ACLU don't exist to serve their original mission statements or even their namesakes, they're just arms of the DNC and pushing a political agenda and only care about trying to win national elections. If the democrats reversed roles again and somehow became the party supportive of Israel, the ADL would become a zionist organization overnight. They have no sincere beliefs, just cynical politics. They're not even capable of some jewish conspiracy to replace white people, because once they realize that importing a bunch of highly religious catholics from south america is going to backfire on the DNC in the long run they'll probably become the pro-deportation lobby as well
