I think the point is clear enough. You asked for evidence and I provided it, you kept pushing the point, so...
Back on topic, you mentioned Aztec (as far as I know there is no such religion) and you said you could also have said christianity.
Which disregards the fact that christianity has undergone massive reform to keep up with present times.
Can you elaborate on why you see christianity as being equally or more barbaric than islam?
Seems like a weak argument to me.
Oh and bear in mind the year is 2011, we are far from living in the dark ages. So modern context would be more relevant, thanks.
