Prisoners in Xinjiang are systematically gang raped and sexually tortured, sometimes publicly. If you look in the wikipedia link you will find details on exactly what the sexual torture involves. Unless you have a thick stomach I would not recommend reading it.
This isn't even half of the crimes against humanity in that region. Men, women and children. All of these claims have been corroborated by multiple independent observers. One million people, none of which are convicted of a reasonable crime. Just...let's step back and realize what we're talking about here.
Knowing this, do you believe there is a valid moral equivalence between this and even the most steel-manned, critical interpretation of US-prison-labor? Do you believe that the existence of US prison labor, even with all its (far more nuanced than you may give it credit for) problems precludes or somehow invalidates boycott and criticism of products connected to atrocities in Xinjiang? If so, why?
