This analogy is WAY off. Have you discussed your theories with any rabbis? Sephardim, Lubavitch, Misnagdim, Ashkenazim-- all believe in the 13 principles of faith, and believe in the Oral and Written Law. They are ALL Jews. The Karaites do not believe these things. They are NOT Jewish.
No, the analogy is perfect. I wasn't speaking about what Orthodox Jews think. I was speaking about what Karaites THEMSELVES think. Just as a Chabanik thinks he's both a Chabadnik and a Jew, a Karaite thinks of himself as both a Karaite and a Jew.
Are you just dense? I've never claimed that Orthodox Jews consider Karaites to be Jews. I've claimed, and my analogy went to show, that the Karaites think of THEMSELVES as Jews.
