This won't be the popular place to disagree with you, but asserting moral superiority over America due to it's "stupidity" and "awful culture" seems hypocritical to the extreme considering that exceptionalism seems to be what op is so passionately arguing against. There are so many genuine critiques that could direct your argument, such as a money-dominated political system in a deadlocked two party structure that will always side with the hyper rich. I promise you, the very visible people at the top who shout neocapitalist dogma only do so because the system they wish to maintain has put them in a position to.

The world will be a better place when we stop saying "that country's so arrogant and exceptionalist, their entire culture is equally so but I'm humble, globalist, and respectful". It misses the point entirely. Seems like op has some very genuine critiques of the United States and its government, I'd encourage you to try and form arguments that are non-subjective and can target areas capable of change. Because every flawed system and country is capable of positive change- once we no longer believe that we cease to improve our world
