Splain what you're saying a bit better please.
What I am saying is that at the time, no one, from a Christian standpoint said anything about what the Crusaders did or even knew what happened except that the crusades were "glorious".
Much the same could be said about the Muslim world these days. If there is a car bombing in Tel Aviv, someone in Saudi or the UAE won't know much about it unless they see it on TV because chances are their Imams will tell about how "Glorious" it was.
It doesnt absolve anyone of any guilt or association to the acts, but the surroundings are simliar.
