This is not controversial, which makes the "anti-racist" branding of the ADL more ridiculous. Jews were involved in the slave trade and never wanted to renounce it or their role in it. Guess where some of the money for Israel came from, and why they present the ideology they have chosen.
It's not a conspiracy theory to trade in common knowledge, for at the time, Jewish support for the KKK was not controversial. Those involved in the slave trade backed a resistance movement to restore the slave power and defeat Northern aggression as they saw it.
There was the original Klan, which was much like other secret societies, and the "revived Klan" that upheld Eugenics and repurposed itself as a vanguard movement of the eugenic creed. One thing that is often not considered is that for a long time, the purpose of the Civil War was not settled. The Klan wasn't just a "shady secret society", but a club for white men to feel they're part of something. They never stopped being a "thing" until the last third of the 20th century, where they could metamorph into various interests but the biggest was the Religious Right (i.e. Nazis).
Probably the biggest "blocker" for understanding this is believing that anti-Judaism was the leading purpose of the Nazis rather than eugenics and hatred towards any form of democracy. For the KKK, their concept of "democracy" entailed a franchise limited to whites of good standing who turn out to vote for their masters, but this was not enough, for eugenics cannot tolerate any iota of "democracy". Eugenics also requires the interested parties to go to war over the spoils, and so this would not be unusual to likeminded people. They laugh at the idea of peaceful coexistence even with "allies", and so you see a lot of strange bedfellows as long as the "greater enemy" of the broad masses are defeated. And of course, there were Jews perfectly happy to throw their own to the wolves to save their fortunes. The slave power promoted that throughout the world.
