More on China: "Trying to eradicate ethnic groups identity"

So I was scrolling around on reddit and I saw this:

Thoughts on what's happening around the world? Not only China, but even the USA has children and families in concentration camps at the borders. Doing a quick google brings up a few more articles about other places as well worrying and undergoing these kinds of situations. I feel like I keep hearing about all different groups being persecuted in all parts of the world and my heart cries for them. Do we all think this is okay and so that's why nothing is being done? Is anyone actually aware of everything going on? There's so much to keep up with these days with 20 new news topics coming out a day that I feel like my head spins with the info. It makes it impossible to keep track of anything. We are constantly distracted by something else happening. Sometimes I feel like the world is so fake right now, like it cant be real. Do you think humanity understands the gravity of our current world situations? It's easy to look back at history and say "man those guys should have known better!" And mock what happened. It's harder to learn from history and see where your mistakes have been. "Those who do not study history are bound to repeat it" I truly think that is happening currently. History repeating due to people not wanting to admit mistakes/faults/failures. How can we all sit by and just let "cleansing" happen? Especially in today's world?
