None of the sources conclusively prove that there is genocide, and neither are there sources disproving it completely. That of course means that no one knows for sure if the claim is true (except the Chinese government). Feel free to believe that it is false, but I am going to believe that there really is such a thing going on.
You have refused to engage with them.
I have refused to engage with them? That's a ridiculous claim.
it's you refusing to engage in good-faith discussion.
You sound hypocritical. You are not even in good-faith discussion.
I honestly find it hard to believe that there is any degree of democracy in a country where the government regularly silences words on its social media. The local officials (the mayor, legislators, and the president) where I live are all elected and I'm pretty sure that's already more than what China has. Their high approval rate is due to the fact that people don't know that their government can be better.
