I never attempted to justify the crusades. Guess it's easier for you to put up a false argument when you can't refute a point.
Let's try it again. If Christians were allowed to legally proselytize in islamic occupied lands, initially, more people would be given the opportunity to exercise God-given free will , and ultimately, fewer people would be born into islam (read: satanic deception).
Looks like some (little g) god is afraid of the competition.
Therefore I assert that islamic religious beliefs are not as you suggest just "a geographic or familial accident", but is in reality, brainwashing by a psychotic demon.
This is the kind of silliness that makes it tough to take you folks seriously.
Very good.
