Shalom Rafeli18,
Yes indeed Rabbi Kahane was a tzadik (Righteous Man) and he what he said was pure Torah truth. He did not mince his words, he spoke the truth from the hip, and knew that his words were the Torah of Moses from Sinai.
I am what is called a Baal Teshuva, a born Jew who went off the path during his mid life, and came back (Did Teshuva/Repentence/Return) to the faith of my forefathers. I have a long story about what brought me to do teshuva, but one thing was the fact that my brother was a victim of 9/11 (he worked in the WTC). That event, along with some other personal travesties, brought me to return, and accept an Orthodox lifestyle (which a bit of bumps and potholes along the way).
I find that the only answer to the haters, both the nazi Jew haters, and the islamic Jew haters, is to concentrate on our Torah, bettering ourselves, and being strong against all of our enemies and never backing down in the face of terrorism or threats. Jews can tap into untold Blessings from the Holy One, Blessed is he. We were promised this in the Torah, and my ten years of study of the Torah teach me that through our own betterment we can reap the rewards of this physical world, and at the same time we ensure our eternal world and reward.
If you would like to learn about a major focal point of the Torah, and the faith of Jews, you should begin by studying the history of the destruction of our Holy Temple. We are currently in a period just prior to the date, which is this Tuesday (starting Monday night), when both of our Temples were destroyed (first by the Babylonians and second by the Romans).
Jews who mark this occasion do not study any Torah except for the book of Lamentations, and other Talmud and Prophets portions which recall those very sad times.
