1. The "modern American self" is best defined by (the tension between) Franklin and Rousseau. 2. Rousseau believes X and Franklin believes Y. 3. "Modern America" (society? politics? government?) flip flops between these two, though they are "almost entirely incompatible". 4. The author claims one of them scales, and says he likes it.
I engage directly with claims 2 and 3.
I think 1 is another completely absurd simplification. I do not address it, or claim 4. I don't see how that constitutes lack of engagement or quibbling. Perhaps I could have written an essay refuting OP with many citations, but I don't think that level of work is required to constitute legitimate engagement.
I guess you're probably right that my comment is more shame than content, maybe 60/40 shame to content, I should have dialed that down a bit. Fwiw I think it's fine to be simple-minded and ignorant, I am both of those things about many topics, but then your writing and argumentation should reflect your lack of knowledge and certainty. OP's article is, otoh, full of hot air.
