One sentence that throws the problem of evil out of the window.

[I_am_not_mafia]

And I keep trying to tell you that an objective fact can be measured without the use of brain based personal feelings, tastes or opinions.

So, too..then, could a moral fact.  That;s what;s being discussed in objective morality.  Moral facts of a matter x.  Those opinions, as you'd put it, which correlate to facts, and can be demonstrated by reference to them.

What is a moral fact?

You can't do this for morality.

Why not?

I am quite happy to admit to being wrong if you can tell me how the morality of an action can be determined without the use of brain based based personal feelings, tastes or opinions.

Even if you were to use a machine learning approach to recognise neural firing patterns, you would still have to use those brain based personal feelings, tastes and opinions to train it on what was right or wrong.

So your moral opinion of livestock processing isn't based on facts, then, because there are none to be had and/or no way to access them?

Moral opinions and facts are not the same thing.

Objective facts are independent of any moral opinion I or anyone else will form. Nor do objective facts change because of the moral opinions that people have. Science wouldn't work otherwise.
