You just stated that America is not exceptional.
let me know what your final answer is on this.
Regarding sharia law
Honestly I don't know much about it. I generally support laws that protect freedoms, civil liberties and so on. I suspect that's not the case here but I'll look into it and provide a final answer once I get a final answer from you too. 
"You just stated that America is not exceptional."
That one statement proves your bias and how you hear only what you want to hear. Because America has done things that other countries has done you immediately read that as me saying America is not exceptional.
No where do people have more opportunity than they have here in the U.S. We fought a war and loss more Americans than all the other wars combines to overturn the institution of slavery. What other country did that? It was in America that the idea that you are not stuck in your class and can rise above it based on your ambition and willingness to work hard and your leaders are not just born into their positions like with monarchies. Women's rights and their rights to vote took root here. Just like Civil rights and passing laws protecting minority rights. More people want to come here than any other country because of the opportunity and the concept of the American dream. Since this is a bodybuilding board, it was Arnold who said many times that he would never have been the success that he is if he didn't come to America. No one was willing or able to fight Communist expansionism as we did. It's such a tragedy that ingrates like you have no idea what kind of life you would have if it wasn't for America.
But your mind is already made up. You hate America. You blame it for all the ills of today. You claim that there isn't a "single thread of evidence" that America has done any good in this world. You cannot imagine what the world would be like if America never existed. Fascism, Nazism, Communism... take your pick.
