Genocide absolutely has to do with severity even if the technical criteria do not explicitly define said severity. That is why more human right lawyers have about been vocal about a genocide occurring in Gaza than have about one occurring Xinjiang. An assessment has to deem war crimes and human rights abuses to amount to genocide along with intent determined through those actions. I urge you to read the OHCHR’s report on Xinjiang and see how they choose their terms carefully despite having evidence for a array of different human rights abuses: www.ohchr.org/…/22-08-31-final-assesment.pdf
