What a ridiculous argument tactic (“since you can’t reckon with the totality of a system according to my arbitrary standard you can’t critique it”).
Furthermore, complaining about the use of “you Americans” is childish tone policing and something one does when they are unable to address the merits of an argument. Maybe if you had an actual argument you could think up something else to share, rather than attempts to stymie discussion because it appears to make you uncomfortable.
Lastly, you brought up nationalism. From my vantage point (as another American) it looks like you’re just trying to shut down debate instead of face the reality of the outcomes we Americans have engineered for our most vulnerable populations.
