How much pain can atheists withstand ?

[Mister Agenda]

All the facts that are available to the humanists your refer to, are also available to the theist. The atheist, however, doesn't have the framework to assess any given situation as bad. A child needlessly starved to death is, strictly speaking, a net evolutionary gain in the cold, indifferent universe that your worldview promotes. A child's starvation to death is evolutionarily beneficial, as there will less vulnerable life forms consuming scarce resources without making any contribution to the world. Not a healthy perspective huh ?

Evolution is a description of what happens in nature, not a prescription for how to act. I agree that's not a healthy perspective, but I don't know a single atheist who holds that perspective. Social darwinism is incompatible with humanism.
