Regarding your point 2), yes: whataboutism is a real problem and an impediment to productive discourse. But in questions of moral authority, the "But America" whiners have a certain point. America's internal conflict and state-sanctioned misconduct is not a secret to the world. If our citizens cannot be seen making good-faith efforts (and progress!) towards justice and equality on our own soil, who would follow our example? With what credibility? I view it as less "But America killed George Floyd, so let's give up on other oppressed people in the world," and more "But America killed George Floyd, and then peaceful Americans withdrew their consent from the violence conducted in their name." It is a way of leading by example in the spheres where we actually have influence. We can chew gum and stand in solidarity with Uighurs, at the same time.
