Islam is very peaceful and tolerant

In this USA Today article, a University lecture in Sweden was interrupted by Islamists allegedly headbutting a Professor and shouting "Allah Akbar!" The professors two crimes, one depicting the alleged Prophet Muhammad as a dog and two, showing a video clip from an Iranian artist discussing homosexuality and Islam, specifically that engaged by the alleged Prophet Muhammad.

I note that a) if Islam is peaceful, why the head butting and b) if Islam is tolerant why the subsequent reaction and stifling of speech when Muslims disagree with another person's viewpoint/opinion/etc. For example, when the National Endowment for the Arts (NEA) funded "art" showing the crucifix in a jar of urine, or the Virgin Mary smeared in feces, Christians didn't rise up and burn down the exhibition or slit the throat of the artists, or even manage to get funding to the NEA cut off. This however, doesn't fit with Progressive/Leftist/Liberal world view that Islam is the Religion of Peace and Christianity is the Religion of Intolerance and Violence (i.e. Crusades).

I guess in a way, this is why Helen Thomas can tell Jews to "get the hell out of Palestine" and "go back to Auschwitz". It's cool to be pro-Islam and anti-anti-Islamic-religions (think about that double negative for a second). If it's not cool, then it's at least hip to be passive towards Islam, which is just another means of being for it; like appeasing tyranny, you only get more of it when you refuse to confront it. When one views the current ongoing events re: Israel's legal blockade of Gaza, one can see why the world automatically sides with the Islamists-propagators and anti-Jews. Not even the U.S. is backing Israel's right to blockade Gaza, therefore the U.S. is enabling anti-Jews to continue their campaign at breaking the Gaza blockade.

Charles Krauthammer had a great article in the Wall Street Journal stating, "Because, blockade is Israel's fallback as the world systematically de-legitimizes its traditional ways of defending itself -- forward and active defense." "It's the point understood by the blockade-busting flotilla of useful idiots and terror sympathizers, by the Turkish front organization that funded it, by the automatic anti-Israel Third World chorus at the United Nations, and by the supine Europeans who've had quite enough of the Jewish problem." "The whole point of this relentless international campaign is to deprive Israel of any legitimate form of self-defense." Therefore one could summarize this campaign as essentially pro-Islamist and anti-Jew, with the U.S. taking the position of passivity. We can all take comfort however, based on the few examples I've listed, that we can expect the Islamist Palestinians to treat the non-Islamic Israelis with peace and tolerance.
