Nope, but nice spin.
1. Saying a birth rate policy should be applied universally to all citizens of China is not justifying such a policy based on a 'believed “correct” ethnic ratio.'
2. My point about the growth of the Uyghur population was a separate point, which is that from my (apparently naive) understanding of what a genocide is, the population would typically decrease after it occurred, not increase.
3. Forced sterilization is ongoing in the criminal justice system in the US, at least as late as 2011. Don't think it is equivalent because it is not nearly as broad based, but in the 80s and 90s it was a not uncommon remedy offered (mostly) to black people to get probation instead of jail in exchange for sterilization, as well as just straight-up court mandated sterilization.
I also don't think the CCPs child policy is justified, but I do think that it should be within the realm of actions that the state can take.
