I genuinely went to read this in good faith since it's The Intercept (I know it's not great, but it's not CNN) but decided to do a quick text search for Zenz just to make sure. And of course, the whole fucking thing is full of Zenz.
This is just ridiculous at this point. I really don't want to be a genocide-denier if there is actually one happening, but for fuck's sake this is just ridiculous, LET ME SEE ONE REPORT ON THIS WITHOUT ZENZ ALL OVER IT.
who translated those documents?
You'd have to ask the author or Ryan Tate. The author is active on Twitter so they'd probably answer.
I don't have a Tweeter so w/e, I only bring it up because Zenz has a habit of feeding documents through Google translate and having his conclusions dunked on by people who are actually fluent in Chinese
