Bloodline purity is Nazi and KKK level shit. All Jews are indigenous to Judea, because the Jewish nation is indigenous to Judea. Our "family" is of Judea. It is what defines us.
Sadly they don't even see the antisemitism in their ideology. Of course part of it has to do with a poor understanding of indigenous status and nations. But what can I expect from people who aren't trained anthropologists?
They hold a great deal of ignorance, but I'm not going to apply the label of "bigot" to them because they truly believe they're doing what's in the best interest of the Jewish people. They're dead wrong of course and they're causing great harm to the Jewish people, but they don't see that.
Sorry, but you're not going to convince me by using "commie" as an insult. Plenty of wonderful, kind communists were murdered by Hamas on Oct. 7th when they rampaged through the Kibbutzim.
