Yeah I think this arises from a fundamental gulf in understanding between the leftist and non-leftist. From the leftist end, it seems obvious that the other party’s opinions are formed by US capitalist propaganda (corpo media and mainstream HS history), so pointing out America’s flagrant hypocrisy when it comes to human rights seems obviously relevant to try and make them question the credibility of the info they’re leaning on. But from the other side, they think their opinions have been formed by Objective and Trustworthy neutral sources, so playing the comparison game seems like a diversion or like it comes out of left field.
