To Republicans human rights is all about forcing Christian values. The history of the Republican Party is a joke when it comes to human rights. They have a history of believing in white supremacy and by its nature they want to violate human rights to achieve that. They think just because they can say it, it must be true in their heart because God would've struck them down with lightning if they were lying. That's a theme among Americans like when they watch and read TV news and media and when they like something said, to them if it were a lie, there's some authority that will prevent them from lying to the public so it must be be true.
This is all about forcing Christian values onto China and therefore they will be in control of China. Freedom of religion is a part of human rights. The Republicans just don't tell everyone that Christianity is the only religion you're free to choose from. That's how they put it under the guise of human rights. It's like when the alt-right says their freedom of speech is being violated when anyone dares to counter them. They think freedom of speech is no one can question what they have to say or else their rights have been violated. That means they only have the right to free speech and everyone else has to shut up and say nothing. It's no different from how they cry they believe in democracy but they had slaves violating people's human rights at the same time.
