I don't think so. How many people talk about how everything changed on 9/11? I've read a bit about the history of the crusades, and there have been slaughters (on both sides) that make 9/11 look like a day in the park. This has been a monumental struggle going back 1300 years or so.
I don't think so. Well, thank you for sharing your opinion.
I am just going by the dozen or so books I have on Islam and the Crusades specifically, plus all Encyclopedias and reference books.
If you would rather fly by what you think, knock yourself out.
