Or a policy angle. Or a real person living in the US angle.

They explicitly said that they're not living in the US! This what I mean when I call the comment substance-free; it's made up of words and sentences, like any other comment, but you immediately recognized that it would be silly to engage with the text in detail. What the commenter means is "RAAAAGH", so a person living in the US might agree because they also feel "RAAAAGH".
