“The Christians got violent one time a few years ago and went berserk killing over 1000 muslim”
Not sure “berzerk” is the right word here.
How about “sane”?
How about “righteous”?
How about “on offence”?
How about “to insure their family’s safety”?
Others?
They went berserk for the very reasons you stated and they are the kinds of things worth fighting for with passion.
The Christian Forces during the Crusades fought with a ferocity and inhuman savagery that horrified their muslim enemies.
