The problem is we live in the present.  We have to deal with muslim terrorists today because muslims are the predominant terrorists today.  So stop with the crusades and the Spanish Inquisition crap, it doesn't mean anything today when there are muslim terrorists beheading hostages, flying planes into skyscrapers, shooting up offices and nightclubs, running down shoppers in markets and fireworks displays, shooting up magazine offices and I'm sure I missed tomorrows attack but you get my point.
