Under "naturalism" how does it do that? because Under Christianity, with God, it is explained why it is wrong as we have Moral written in our hearts and it is Perverted, Abusive, Sickening, and Disrespect, all 4 which do not exist under "naturalism", rendering "naturalism" false as "naturalism" would condone, rape. rape is really wrong, therefore "naturalism" is false.
"atheist" can be moral, but have no foundation for them as under "atheism", morals would be illusory, which is false since Morals are real, which makes "atheism" false.
That's why "naturalism" is false, rape does cause physical harm(from the mental/Spiritual harm), on a purely physical basis(naturalism), it would not be wrong, which is wrong, so according to your worldview, You have to be the one kidding me.
Advancing a species, notice how sickening the "naturalistic evolutionary" worldview is and how it should be abandoned, literally under "naturalism" rape would be advantageous, get out of here with that, rape is sickening and is one of the worst of worst, maybe the worst, yet under "naturalism" wouldn't be.
"naturalism" is Factually false, it has to be.
Under "naturalism" there would be no difference, however that is very obviously false as rape does cause harm, rendering "naturalism" false, but since you do agree with me that rape is wrong, you disagree with "naturalism", "atheism" and "humanism".
Under Christianity, Immaterial properties like Morals, perversion, dignity, self worth, abuse, etc exist, rape is perverted and despicable, under "naturalism" those things don't exist, which is false.
