It is entirely possible to recognize the things that are good about the US while also seeing the very terrible things. Nothing is perfect and if we tell ourselves it is by criticizing anyone who says otherwise, we are robbing not only the world but ourselves of any opportunity to make it better.
All I see on your timeline regarding us is blind sycophantic behavior. It's not self-loathing or sophomoric to recognize a point of policy or behavior that is not conducive to the wellbeing of global markets and wider well-being. We haven't been behaving in the best interest of the common good, or fellow Americans, nor even private interest for decades now and a little realization of that is just seeing objective reality.
