I'm talking about the ones that go "God doesn't exist", "it's all bullshit", "your God is terrible" and then go "well....why aren't I going to heaven then?"
The last question is usually an argument against God. It's usually a part of the "God isn't just" argument used to discredit belief in him. People who don't believe in the Christian God and then ask the last question, usually don't believe in Heaven either.
