I absolutely agree that transplanting US talking points wholesale into non-US frames of reference is something that's often done blindly and never really applies.
But the reason for this is that the issue is nuanced and has a lot of local context that needs consideration in its own right. It shouldn't be used as an excuse to dismiss the existence of systemic racism in your own country.
I think the above quoted line is such a pity as it truly undermines the rest of your otherwise excellent comment.
