There are likely more authentic Christians in China than there are in the USA, according to many ‘aware’ estimates.
Perhaps, but they also have four times the number of people and there are tons of obstacles for them to worship in China. On the plus side, China is moving in the right direction while the US is moving in the wrong direction. And as far as US universities, they are mostly hostile towards Christianity, but at least in the US you can't be imprisoned for it yet.
