Of course, in China, it's illegal to spread religious lies, hate, religious fiction, and complete nonsense.
China has decided to reeducate religious extremists in an attempt to bring them into the 21st century, and if they don't comply, they end up in jail for spreading obvious lies.
I hope they also got the priest that decided spreading religious hate and bullshit to people in China would be a good idea.
Don't like it? The west's answer is to let religious extremists propagate until they commit terror acts, then they are arrested. Then the same priest that radicalized the last religious terrorist keeps on radicalizing more, and more people until retirement. If it happens in another country, we declare war and kill millions of innocent people along with the radicals. I don't consider this a better solution in any way.
