Is the Uyghur genocide real?

I have been researching this with a critical eye and there are people speaking about their family in the camps, but when you address this with a leftist crowd, a good amount will deny it. Is there any evidence that the Uyghurs are not being systematically targeted by the Chinese government? I’m a leftist, but all states have their flaws and I feel like people are just denying that this is happening because “china’s communist so they must be all good.”
