...and I feel for the peaceful Muslims whose name is being tarnished by these extremists.
A strict reading of the Quran, the traditional scholar's interpretation,and the hadith suggests that they're actions aren't condemned by the good book. Considering that the peaceful verses were abrogated by the later more violent verses in the Quran, I don't see how any moderate and peaceful muslim can convince a strict Imam (who have all the control of the people btw) to choose the way of peace. Just look at the imams in Saudia Arabia, Yemen, Afghanistan, Iran, etc. and you will see that those who are hardcore fundamentalists (taking every word of the Quran and the hadith extremely seriously) generally endorse these violent acts (especially towards Jews).
This is why moderate Islam is a joke - because it's simply not a true representation of the religion.
I'm not complaining that there are no peaceful Muslims - but peaceful Muslims are those who don't take the Quran and Hadith seriously.
I can garauntee you for a fact that those who were protesting in Sydney were the ones who took their religion seriously (going to the mosque continually, reading the quran, reading the hadith, etc.) and those at home watching their fellow brothers and sisters in Islam make a fool of themselves didn't.
