thats correct an atheist can never say that what Nazi germany did in gassying women and childern was absolutely wrong nor Pol Pot or Stalins murder of his people.
Likewise if a paedophile broke into into your home or muzzaratis and raped and killed your son. An atheist cannot say it was absolutely wrong, sure from your perspective it might have been a downer but the paedophile gets enjoyment in raping kiddies, he is living his own world view out. Without a mind prior to the human mind morals, values can only be relative, a cultural bias or taste. Without God I agree life is ultimately meaningless. But as long as the atheist understands the full consequences of their world view and not lapse into hypocritical statements that things like love and the value of human life are actually real.
As Chucky Darwin put it, if my mind is just a highly developed monkeys brain why should i trust it?
See old Chucky was struggling with the concept of epistemological nihlism.
Likewise if we graciously accept that you believe your brain is that of a higher order monkeys brain the Christian believes that his mind was a precious gift given by a creator. The rational mind versus the mind that has essential come from the irrational, a monkeys brain.
If an atheist is just a cluster of atoms created by some cosmic accident and life is ultimately meaningless you now have two opposing world views to think about or choose.
One that values life and one that believes that life is ultimately meaningless.
Oh boy only a monkey would choose one of those options but which one?
