It's fully possible to condemn both if you're uneducated, yes, many such cases. It just so happens that the Zionists pushing anti-Palestinian sentiment are very often proponents of the Uyghur genocide conspiracy theory concocted by western fascists such as the type of Adrian Zenz.

Unfortunately for them, the widespread video evidence of what an actual genocide looks like emerging from one of the most totalitarian controlled regions of the world (Palestine at the behest of the Zionist entity) has severely de-legitimized the claims of the false genocide in Xinjiang, which only serves to create a "two things can be bad at the same time" narrative to both alleviate the genocidal sins of the western empires and simultaneously manufacture hatred against socialist China.

The "Uyghur genocide" narrative is a form of genocide denialism by calling everything a genocide, which severely undermines the legitimate struggle of the Palestinian people against their colonial oppressor. Thankfully it's very easy to disprove by asking for any shred of video evidence of systematic violence against the Uyghur such as unfortunately has existed in all our social media since the intensification of the genocide against Palestinians that takes place since 2023
