Derech HaMelech, are you talking about the articles of the Neturei Karta. Because I’ve only counted 5 of them in pictures & videos for the past few years…those guys travel so much that it’s hard to understand when they get time to study Torah….
Cherrybim, adding to what you said, there are also many non-jewish Christians in America that actually claim to be Jews. I’ve actually talked to a few of them; they believe that they are Jewish, even though they have NO Jewish lineage.
Furthermore, 1 of my (orthodox) friends was in a carribean island & he told them that he was Jewish. He said that they were ready to kill him, because they (the islanders of African descent) were the true Jews.
