That's some good research.

Some thoughts, though:
1 - Check your sources carefully on this topic -- I find a large number of Islamic sites posting histories of Islam that are pretty biased. To get an objective picture of the history of Islam, you need to either read through the bias or find an external source. Good luck, most of the popular sites (ie, the ones returned towards the top of the Google list) are pretty clearly Muslim operated. When you're reading, the bias will be obvious by statements like the following:
a - "Islam spread" - they fail to mention that it spread through violence.
b - "City XYQ rejected Islamic offers of peace" - which leaves out the fact that peace comes at the brunt of a brutal occupation, making the victims sound like aggressors, despite the fact that there's a Muslim army at their city gates.
c - Those are the only two I can come up with off the top of my head. Just read the Muslim-written Islamic histories carefully.

2 - There's a difference between extremists and fundamentalists. A fundamentalist is someone who believes in the fundamental principles of a thing. For example, a US Marine could be considered a fundamentalist military member -- there are certain fundamental principles that make up being "military," and US Marines tend to embody those whole-heartedly. A fundamentalist Christian is liable to read the Bible regularly and generally live by it. A fundamentalist Muslim is no different.
The question to ask, then, is "What does the Koran teach?" What are the fundamental principles that fundamentalist Muslims are being fundamentalist about? While a casual reading of the Koran will reveal some notable Peaceful-Happy passages, it should be understood that those segments apply only to members of the House of Islam. If you're not a Muslim, you're of the House of War (like that name? It implies that be not subjugating yourself to Islam, you're choosing war for yourself. Neat, huh?). Members of the House of War are afforded none of the generosity, kindness, etc. afforded to members of the House of Islam.
(sigh) I could go on, but whole books have been written about this topic, and some of them are quite good. The bottom line is that the happy-friendly-peaceful Muslims that you find aren't living according to what their book teaches. The ones who blow up school busses, on the other hand, are. (shrug) But then, anyone who can persuade a guy to go be a suicide bomber is clearly a better leader than I am -- perhaps I should take lessons?
