Christians should declare a Crusade on Muslims?

So there's a discussion on the ETM (Eternal Truth Ministry) boards where someone has come on declaring that it's Christians' duty to declare a crusade on the world of Islam. Here's the starting post:

Hi i was just wondering is it right to crusade? we have a responsibility so protect Jews as they are His chosen people so shouldn't we as Christians come together and forget denominations to expel Islam from the middle east ( a land that use to be primarily Christian and Jewish) and protect our Jewish brethren. I know i would support a Crusade in His name even though i am not a Catholic.


To see responses (and maybe join in on it if you like), here's the link to the thread:
