Before I explain this, let me put on my flame retardent suit. OK.
Israelis and supporters of Israel outside the country are about evenly split between Labor and Sharon's Likud. The latter party believes in a number of extreme positions -- that they have an inalienable right to land that God gave them land 4000 years ago regardless of who is living there, that they have the right to wage collective punishment against Palestinians, that they reserve the right to ethnic cleansing, that they have the right to infiltrate and carry out espionage against even the friendliest governments to them. There are many who are even more extremist; here in NYC on cable access, we are subjected to the programming of the JTF, which advocates not only genocide against muslims, but virulent anti-African American and anti-Hispanic racism that makes the KKK look tame.
http://www.jtf.org/ In other words, if Israeli elections and outside Israel support for Likud are any indication, there is about 50 percent support for extremist parties in Israel.
By contrast, of the 1 billion or so muslims, it appears that about 20,000 are actively involved in violent jihadist organizations. Add several hundred thousand passive financial supporters in Saudi Arabia, and you have perhaps 10 percent of the worldwide Muslim population being accurately described as extremist.
The question is all about framing the issue. If you don't consider Likud to be extremist, then there is very little extremist zionism. If you consider Likud and everything to the right of it to be extremist, then I guess there is a lot of extremism among the supporters of Israel. If killing by irregular forces is extremism and killing by organized occupying military forces is not extremism, then I guess the Muslim world is more extremist. But if the technological sophistication of the method of killing is irrelevant, then there is a lot of extremism on both sides.
Everyone should be held to the same standards, regardless of technological sophistication, or "framing" of the issues.
A JTF sampler:
The Mexican Nazis have formed mass organizations with hundreds of chapters and thousands of active members throughout the United States. Through these organizations, they call for the destruction of America and Israel.
Their vicious Nazi Jew-hatred is ironic in view of the fact that self-hating Jews have done so much to promote them: self-hating Jews are often in the forefront of efforts to allow more Third World immigration into the United States, to legalize illegal aliens, to promote anti-white and anti-Semitic "affirmative action" racial discrimination and to promote multilingualism and multiculturalism.
This is important for all white Anglos to know and understand: there are certain groups in this world that the more you do to help them, the more they hate you. For their ugly hatred is based on envy, and since they come from a hopelessly inferior and primitive culture, they will always envy and detest the vastly superior white Anglo culture - and Jewish culture - which they cannot compete with.
Yet as with that other "minority" group that self-hating Jews have done so much for - blacks - the Mexicans have "thanked" the Jews for their help by becoming Nazi anti-Semites every bit as vicious as Hitler and Goebbels.
That is why 94% of blacks voted for the black Nazi Jew-hater Jesse Jackson when he ran for President, even though these black Jew-haters would not even have the right to vote had it not been for Jewish involvement in the "civil rights" movement of the 1960s.
