Quoted for shared opinion, you mean. 2+2=4 is a truth.
Patriotism isn't a form of ego or pride. It's belief in the importance of a way of life, and the willingness to protect it. If you had spent a few years earning your right to run your mouth, you'd both have learned that, and you'd appreciate the fact that you're actually able to share your flawed opinions, instead of using them to spit on this country and everyone who gave it to you, because of the ideals of patriotism.
And blaming religion for violence is just stupid. If you want to find someone to blame for violence, stop using your prejudices to target random groups and look a bit further. I mean, by your logic, all men should be removed from society and killed, because men are far more violent than women. The ratio of violent men to violent women is far greater than the ratio of violent religious people to violent unbelievers of any faith.
By the way, America wouldn't exist without religion, patriotism, or violence. Make no mistake, the concept of necessary violence absolutely exists, and that'll never change; even in a world without religion, a world without patriotism, pride, or egos, it would exist. Because your perfect world would require tyranny of the kind the world has never seen.
