Sorry for butting in with my two cents here...
It's all too easy, especially when discussing politics, to rely on a pre-established narrative shorthand in dealing with other people doing their best to summarize complicated views in an imperfect medium. I'm guilty of this myself; MSJ, I had you pegged as a Trump supporter/Bush guy/hater of Obama/etc., largely because the views you've expressed in the thread we've argued in don't easily fit into my preexisting mental image of a Trump critic/Obama voter/liberal/whatever. Obviously, people are more complex than simple mental shortcuts can convey adequately, but it was all too easy on my end to fall into the trap of "vocal patriotism + support for the Iraq war = Republican = image already formed in my mind regardless of the situation's reality." Same on tleilaxu's end, I would assume.
As to his comments, they were quite obviously a caricature of Americans-as-viewed-by-Europeans to me; but I traffic highly in countercultural and anti-American sentiment, so my mind already possessed the cognitive detours necessary to see the statement as intended. America's liberal party is well to the right of most European nations' centrist platform, we're renowned for our cultural arrogance worldwide, we lead the world in obesity and overindulgence, we love our guns, and even as a die-hard patriot you have to admit we've had a bit of an issue with race and police brutality in our distant past recent past last Thursday right now. I doubt he intended any direct accusation of racism against you; but again, all too easy to fall into that mental shorthand, and assume the American making American statements is the strawman American fitting the negative stereotypes established, reinforced and exaggerated.
