Noahide ranking of the four gentile religions

1. Islam - most Noahide because of its strict monotheism
2. Buddhism - not as Noahide because it is an atheist philosophy
3. Hinduism - actually idolatrous because it does have a pantheon of deities
4. Christianity - most offensive to God who has forbidden idolatry and blasphemy because Christians are required by the Doctrine of the Trinity to be idolaters committing the Supreme Blasphemy of worshipping an executed revolutionary convicted of blasphemy as the co-equal of the God of Israel who is also Allah
