We must do our best to change their views. I have seen this too, many otherwise good Jews who turn their backs on Kahanism and the Jewish ideal. I have heard the ideas that JTF is radical, extreme, haters, nazi-ish, etc... But I know that they are only listening to the propaganda that the enemies have put out there.
Kahane spoke the truth and the truth has a way of making itself known. One of these days we will be able to tell these Jews who are blind that we were right all along.
