One mans jihad is another mans crusade.
Well, if certain portions of America were overrun by the forces of Islam and those overrun were forced to convert (if Jewish or Christian*) or accept dhimmi status, I would have no problem participating or calling it a crusade. You could call it a jelly roll, for I would care.
Which is pretty much what happened to the lands the crusaders fought over: formerly Christian, overrun by the forces of Islam, Christians fighting to get them back.
Heck, there were "crusades" up through at least the 17th & 18th centuries, as the Ottomans fought up through the Balkans and laid siege to Vienna a few times in that period.
* RevDisk, BP, and fellow pagans would not have the luxury of practicing their religion as dhimmi subjugated citizens. Pagans get to convert or die, period. If it came down to it, I'd claim y'all and forge records of your baptisms in my family Bible to give y'all cover..."Oh, yeah, those guys are
Eco-Protestants. Never heard of them? Well, there
are over 15,000 distinct Christian denominations in America. Think holding church in a stand of trees is odd, lemme introduce you to my charismatic buddies up in the foothills. Got any antivenin on you, perchance?"
