2 points Starchief-
1. China isn't nominally Atheist. They believe in gods. They don't believe in Monotheism. But they do believe in gods. So that rules out Atheism. Source- I'm married to an Asian born Chinese. There may be some Atheists, but they aren't are even near close to the majority at all.
2. Death from practicing Christianity in Islam nation? That's also not even true. Indonesia who has the largest population of Muslims in the world absolutely allows Christians to practice their religion freely. Malaysia (I have lived there off and on for about a year and will be retiring there) certainly has many many Christian churches in Kuala Lumpur.
The death penalty is for Muslims who reject Islam and embrace another religion. This is in countries in which Islam totally dominates. Malaysia is a multicultural country (so I'm told). 61% Muslim, 20% Buddhist, 10% Christian, and 10% others (rough percentages). Islamic leaders are predicting that Christians will outnumber Muslims there by 2100 if current growth rates continue. They are quite concerned.
