Is it okay if I burn one of every major holy book and a science textbook at the same time?
Only if you don't publicize the burning. Unless they happen to be donated to you for free, I don't know why you'd waste money to do a pointless action like that.
I'm not sure if it's due to the US media or the Arabic media furthering the goals of anti-American Arabic politicians, but compare the amount of anti-American hate and threats of violence in Islam with any other major religion. As a % compared with total Muslims, and as a % of total Muslim media time. You don't hear stories about Islamic leaders condemning the kill-em-all route (You have to dig for them, for some reason).
Relationships with Islamic countries have always been shaky, starting with the carving of Israel out of Palestine and the constant defense of Israel from Islamic countries. Our occupation of several Islamic countries doesn't help us either. Add on to the fact that the US has nukes while it tries to de-arm countries like Iran, and you can understand why they hate us so much. People in America constantly complain about incompetent police and politicians, but that stuff is the norm there. It's incredibly easy to pin the blame on America, especially with the accidental killings of innocents and cruel actions of some of our soldiers.
Regardless, all this 'Koran book burning' is legal in the United States and people have the right to protest by burning it. And people have the right to protest you protesting. There's just far too much attention on "O NOES, how will people in other countries react!?!?"
Sure, people have the right to protest this in the US, but of course we're paying close attention to this. Our troops are in Iraq and Afghanistan, so they will be the ones that will take the brunt of our actions. You don't show your worst in a job interview, and likewise, you wouldn't want to have Americans burn Qurans when America is currently trying to pacify those countries. Quran burning sure doesn't help America garner any foreign support, which would be really helpful right now.
