Re: Why do religious people think they must prevent everyone from going to hell?
Where did you read this?
Atheists don’t believe in God or at least the supernatural acts of deity.
Morality has nothing to do with it.
Atheist philosphers *“assert that behaving ethically only because of divine mandate is not true ethical behavior but merely blind obedience. Baggini argues that atheism is a superior basis for ethics, claiming that a moral basis external to religious imperatives is necessary to evaluate the morality of the imperatives themselves—to be able to discern, for example, that “thou shalt steal” is immoral even if one’s religion instructs it—and that atheists, therefore, have the advantage of being more inclined to make such evaluations. *”
BTW I’m not an atheist, but I think you have them pegged wrong in terms of the morality/ethics thing.
