First off BT doesn't stand for 'ben Torah.' Secondly the "I'll go run and ask Chaim, he disagrees with you" argument is rather cowardly and intellectually dishonest. Rabbi Kahane ZT"L made his position very clear, every Jew belongs in Israel. Period. That doesn't mean he would be disrespecting a religious rabbi for choosing not to, or not yet returning there. And it doesn't give you a right to disrespect and slander Jews outright with ad hominem attacks 'because they don't live in Israel.' And G-d forbid you should disrespect a rabbi for it. Who do you think you are? You can choose to disagree with the rabbi's decision to live somewhere other than Israel citing rabbinic tradition and others greater than you who hold that opinion, such as Rabbi Kahane, but that doesn't make a person 'invalidated.' And I think we both know your attack on Tzvi's post had nothing to do with that, at least it didn't seem so. You called the rabbi's material "shas-like"...
In fact, Rabbi Kahane held onto his own dual citizenship because he felt it important to get his message to US Jews and tell them to keep mitzvot, support Kahane's party, and go live in Israel. Rabbi M, according to his biography, is on a mission to get secular Israeli and American Jews in the US more connected to Torah. I'm not sure how you have determined that I'm an extremist, but I find that rather odd and humorous.
