This is such ethnocentrism smacking bullshit. It's unfounded stereotyping of a country that's I'm going to guess is more culturally, ethnically, and ideologically diverse than you are used to.
For starters, I didn't notice any citations in your claims of academic relevance. Have you read papers from reputable institutions that support your positions as their central thrust (rather than a side note or speculation)? If so please cite one and let us know how many of your points are part of its central argument.
Taking it down a notch from academia, even the Wikipedia article on American stereotypes does agree with your list. Too many biased Americans on WP? Even anecdotally in countries I've lived and stayed in, many people were happy to share their American stereotypes and I enjoyed the discussions, but they never mentioned your list.
Some of the things I'm used to hearing: Americans are fat? Not a pleasant thing to hear but objectively true. Americans are gun crazy? Not everyone but still, there is solid foundation here. So this is not a matter of (just) being insulted, I simply call into question your ability to back up your specific claims with sound evidence and data.
Finally your claim that self compassion is "fundamentally juxtaposed" to eastern meditative traditions is incorrect (I assume you meant to write opposed). On the contrary, it is vital component of some practices and one of the first things studied (https://en.wikipedia.org/wiki/Mettā#Mett.C4.81_meditation).
With everything happening in the US right now the last thing we need is people making false assumptions that all of us support the same leadership, same homogeneous viewpoints, same personal failings, etc.
