Correctamundo. AS HAVE SOME MUSLIMS. There are over a billion Muslims - if they all thought and hated in lockstep like you seem to believe that they do, do you honestly believe that Israel would still exist? That the US would still exist? That any form of government other than a theocracy would still exist in the world?
So, we can do things that we should not.
Your train of thought just had a derailment. Two wrongs most definitely do not make a right.
Take great care that you do not become that which you most hate and fear.
You are right. Two wrongs don't make a right, yet that is the argument that was being implied. Christians have done bad things. And those conditions were corrected. Can you say the same thing about Islamics when they do bad things? Do other Islamics speak against, and even fight, other Islamics? Christians did.
Yes. The Koran states that it is the only source of truth, and that anything outside the Koran is evil. As in, being creative, and developing new weapons.
Islamists would nuke Isreal today if they had the power. But their Koran discourages freedom to think outside, well, the Koran. Thank God. They'll use it when they can purchase it.
Quick, how many rifles were developed by Muslims? How many planes? How many grenades? How many books, other than Mohammed stories? How many antibiotics? How many disease cures? How many operas? How many symphonies? How many DNA sequences? How many satellites?
The answer is none. Their Koran forbids it--none of those things are specifically listed as allowed.
Quick, how many infidels have been blown to pieces in the past year?
You see, that is both allowed and encouraged.
Again, good thing they haven't bought nukes (yet).
