Long article but well worth the read. Unfortunately the author is right. We are at the cusp of a new Crusade and the question is will we, as the original Crusaders were, be ready to fight IN DEFENSE of our religions and beliefs?
It might shock you to know that I don't fully agree with the author. Islam is no more monolithic than Judaism or Christianity. There are different sects and different views. Every so often we see some really good articles by moderate Muslims who are clearly on our side. I could post links to a dozen or so if you want. The media doesn't run with them. The old saw: "If it bleeds it leads" applies to our sensationalism driven media, at least in the west. To put it bluntly, I think Ms. Sagamori's article is racist. (Broad definition, as I know Islam is a religion, not a race.)
Having said that there is no doubt that fundamentalist and radical streams of Islam are ascendant right now and they do need to be fought. I think Ms. Sagamori's description of the situation vis a vis the British is sadly correct, her description of Europe being overrun by Muslim immigrants and their many children is correct, and her views on Iran are correct. I'm not at all sure her conclusion is correct.
In the U.S. Muslims, as a group, are not yet a threat. They may never be as Americans, unlike Europeans, don't tend to discriminate against Muslims or keep them poor or unemployed. Within a generation or two I think most Muslim immigrants to the U.S. will be Americans, first and foremost.
Having said that it does make sense during wartime to tighten and enforce immigration laws so that you know who is coming into your country. The Bush administration doesn't seem to want to do that and, IMHO, that's stupid and dangerous. You also need to put political correctness about profiling aside and look very closely at people coming from countries with real hostility to the U.S., and right now that means pretty much the whole Arab world and some other Muslim nations as well.
The Crusades were a defeat for Christianity. I somehow don't think you want to repeat that bit of history.
