Which is why I said I was agnostic to the position of objective morality. It will depend on how you define objective morality. If it does exist then I could see it being defined by harm.
Not really sure if I have ever claimed that I am?
Ok, my definition objective morality is that something is either really right or really wrong regardless of human opinion.
It seems such an unlikely situation that I am struggling to see its worth. The moral approach would be to find out why women have decided to abstain from intercourse and change that rather than just rape them.
Ok, and if you can't convince them to change then what? Harm done v flourishing of the species?
You seem to agree that rape is objectively wrong so the flourishing of the species is going to have to suffer. O wait, the flourishing of the species is your pillar of morality isn't it?
Nothing obligates you to do it. Is that really such a scary concept?
It is quite scary actually. If there are no moral obligations then it would effectively be a free-for-all. In other words, as long as the main aim of human flourishing is continued it doesn't matter.
Since when does atheism say we have no importance? Atheism is simply a lack of belief in God not an overarching philosophy. Atheism has nothing to say on our importance or lack thereof.
Atheism says we are nothing but a by-product of evolution and we are no different from any other animal.
By being beneficial it is good? Not sure about you but I would quite like to continue living and also like my daughter to continue living. Contrary to popular religious beliefs atheists are not, on the whole nihilists.
Being beneficial is good in an objective sense?
You would first need to convince me that they are not connected.
Evolution is morally neutral.
You seem to be really keen on obligation. It isn't obligatory to do good things, but it is certainly beneficial.
Well I do believe that I have am obligated not to murder, rape etc. Don't you? If we are ought to do certain things that there must be some sort of authority surely.
Which seems to me that you actually have no objective reason for thinking homosexuality immoral as you seem to be unable to describe it. Which then makes me think that you have very little way of actually determining if there is an objective morality and if there is what it actually is.
Moral epistemology again. How we come to understand morality has no bearing on whether objective moral values and duties exist.
