you kidding????
"The campaign corresponds with a drive to “Sinicize” religion by demanding loyalty to the officially atheist Communist Party and eliminating any challenge to its power over people’s lives."
What an odd claim when the very quoted sentence says there is....
I think it speaks volumes that you think that sentence shows a causal connection. It doesn't even assert one.
The party allows religions that are loyal to the party, that seems like a very poor form of militant atheism if you ask me. But its seems a pretty strong authoritarian regime.
