Given that your very first piece of evidence of how CNN lies about China is them saying tiananmen square happened, and your "disproof" is just a link to a random website entirely devoted to denying the massacre happened, it's pretty clear why you're not exactly getting a positive response
Edit: The second disproof is literally just the Chinese government saying it isn't true, which isn't exactly thorough evidence
If you exclusively take the statements of a government as unquestionable truth, you're going to be wrong a lot, regardless of which government you choose
Just move to another instance if you're so mad about who they defederate
That's, like, the entire point
