In fact it's mainly simply a matter of identification, it's extremely rare for anyone's ethnicity to be investigated or challenged officially. Where it does matter is in public life, particularly politics and when people purport to represent a group or ethnicity. In the US this undergoes considerable public scrutiny and if a minority group thinks someone is trying to usurp their identity or represent them inappropriately they tend to be very vocal about it and exert considerable pressure to ensure that representation is genuine. Not so much in China. Clearly representation and biases based on ethnicity in the US and west in general is a significant issue. There are many injustices. Nevertheless I think it's a bit distasteful to create false equivalences which trivialises or normalise the systematic oppression and cultural erasure that's currently succeeding at wiping out Uighur identity.
