Honestly, when we're incarcerating almost 1% of our nation, it's not at all clear that that's "far short of genocide". Especially when that 1% disproportionately falls on some racial groups, and that impact radiates out to further decimate those communities. And while it's not outright genocide, it contributes to a very high murder rate in those communities -- some of it committed directly by the government.

If forced to draw some sort of moral hierarchy I'd say yes, it's still not quite up to the organized atrocities committed against the Uighurs. But our disorganized, systemic atrocities are vast, and every other first-world nation is horrified.
