I will agree that Islam is awful and most probably the worst religion if one were to build a good scenario for life in a democratic and rights-oriented society.
Difficult to quantify, but not particularly relevant, as there is ample evidence that pretty much any religion, and certainly all Abrahamic religions, hold tenets that are incompatible with democracy and civil liberties. People who fixate on one (like Harris) do so because they have an agenda.
Now let's go to Sam Harris.
I looked up something Harris had written about the subject, it's old, but it's what I found. Let's lay it out:
If you are under the impression that I am going to accept Sam Harris' unsubstantiated claims and opinions as some form of evidence, allow me to stop you now; he is not an expert on the subject, and does little in the way of research aside from quoting the Qur'an and cherry-picking polling data that supports his preconceived narrative. So, his opinions, on their own, mean about as much as any random anti-Muslim blogger's.
These "specific notions of martyrdom and jihad" that Islam contains may fully explain the character of Muslim violence to Sam Harris, because Sam Harris is already convinced that Islamic doctrine is the only relevant driver of Muslim violence. He examines these issues through a lens of confirmation bias, and is not interested in evidence that conflicts with it. It is wonderfully convenient for Harris to view all of Islam, or even "militant Islam" as some unified hivemind adhering to a single ideology, but that does not make it so.
Now, bottom line: It's there in the Qur'an and it's there on primetime news. The burden is on you to show how what is inculcated into people, especially children, has nothing to do with the people doing exactly that in ISIS.
You are deeply confused about how the burden of proof works. For one, you'll not find any claim from me that religion has
nothing to do with how people behave. My position is that it is one many factors, and far from the most important in light of historical evidence.
The burden of proof is on you and Harris to demonstrate that "
The only future devout Muslims can envisage—as Muslims—is one in which all infidels have been converted to Islam, politically subjugated, or killed. The tenets of Islam simply do not admit of anything but a temporary sharing of power with the “enemies of God.”
"I see it in the news" is not evidence, nor are cherry-picked poll results regarding apostasy; that the
actual numbers very wildly from region to region, or even country to country, amongst people who are devout Muslims, suggests that his generalization is
incorrect, and certainly does not come close to supporting the notion that groups like ISIS are a product of mainstream Muslim thinking. It tells us that there are large numbers of the world's Muslims who hold troubling views, but if we're setting the bar that low, there's plenty of polling we can do of African Christians, Hindus, Latin Americans, Buddhists and Jews on various issues like homosexuality and gender equality, but you won't see Harris or many carrying his particular standard harping on about any of that. As untermensche said, it's only Islam he's interested in vilifying; when it's any other group, he is suddenly thoughtful and deliberative, but all that nuance immediately evaporates when it's Muslims who are in his crosshairs.
Harris' reasoning is reductive and simplistic, and like I said, does not account for the relatively recent emergence of Islamic terrorism as it exists today or the fact that it is targeted almost exclusively at the U.S. and its allies. It is simply a more erudite incarnation of the ludicrous right-wing canard that "they hate us for our freedoms."
