You forgot 5: "This is expression of an individually held value."
and 6: "This is a statement describing a universally (or very broadly held) human value."
Pay attention.
There are
two broad
semantic theories which explain
ethical sentences like "Raping children is wrong".
1. Cognitivism
OR
2. Non-Cognitivism
We are not here concerned with the
substantial theories of ethical sentences which talk about how widely some view is held (i.e. universally or not), but the
semantic category into which ethical sentences they fall.
Paying attention still? Good good..
The ethical sentence "Raping children is wrong." is either truth-apt or not. What do I mean by truth-apt? Well truth-apt means capable of being true. That is, ethical sentences are truth bearers, capable of being true or false.
If it is not capable of being true or false, the ethical sentence "Raping children is wrong", is merely a kind of expression rather than an assertion. It is like saying, "Boo on killing!", or "Killing...Ahhh!" It is no different than saying, "Spaghetti....yucky!" "Or porridge...ewww!"
So the question again is, the ethical sentence "Raping children is wrong", is merely just an expression of distaste because there is no ethical fact that the sentence corresponds to, or it is a proposition capable of being true or false. A non-cognitivist affirms the former, while a cognitivist affirms the latter.
Which are you?
