So say atheist relativists. I can ask them over and over and over again if love (eg. Loving our children) is an objective moral obligation / value. They would love to say “No” but can’t quite make themselves do it. Instead they say nothing at all. And why would they do that? Because atheists know that if there are objective morals, values and obligations, it’s because Creator God exists. If Creator God exists, then objective morals, values and duties exist.
So absurd is the atheist world-view, that atheists would rather say that discrimination against women and even the sexual slavery of children is open for discussion, as long as it keeps out the existence of Creator God.
