I can't speak to the parent commenter's precise meaning, but I interpreted them to mean they oppose the current domestic and foreign policy of US political and business leadership (a distinction that blurs to the point of indistinguishability of late, courtesy of said domestic policy).

I believe that many Americans that were previously dismissive or ambivalent regarding critiques of US activity at home and abroad (either due to patriotism, realpolitik apologia, or general naïveté) are now re-evaluating some of the beliefs they hold about their country in light of the chronic political dysfunction and an absolutely breathtaking extent of corruption being perpetrated in broad daylight today (as well as indications that extensive corruption has long festered among our elite class, surfaced via the Epstein revelations).
