As to what I think . . . the Karaites are a lot closer to Judaism than Reform, Reconstructionist, or Chabad Judaism is.
Madonna thinks she's practicing Kabbalah. Does that mean she is, ChicagoHebrew? Orthodox Jews aren't the only ones who know Karaites aren't Jews and don't practice Judaism. It's a free country. If people want to say they are Jewish even if they aren't, no one can stop them. And again, your analogy to the Lubavitch is WRONG. Lubavitch are Torah Jews. Karaites are KARAITES. I do not care what a website group of believing Karaites says about their religion. It's NOT Judaism.
?????????? What?
Rabbi Kaduri (the subject of this thread, remember?) visited with the Lubavitcher Rebbe. I don't recall that he ever visited with Karaites.
The Orthodox rabbis will keep company with a Reform rabbi, because the Reform rabbi does not deny the Talmud, he simply does not think it is as applicable to the modern world as it used to be. This does not undermine the authority of the Orthodox rabbi
The Karaites, in rejecting the Talmud, reject the authority of the rabbis
