How to easily defeat any argument for God

[Acrobat]

"Reasonable" seems like a fair word to me. 

But that's certainly not the same as "factual" or "self-evident." 

Should we back off a little, and say "in my opinion wellbeing is a reasonable goal, although I have no way of proving this"?

It's a goal. Of course I have no way to prove it in the same way I have no way to prove that passing the exams is a reasonable goal. If I want to receive that uni degree, I ought to pass the exam. It's not a matter of proof or disproof.

That's the ought bit.

The is bit: Harm is bad. Sounds reasonable to me. Can I prove it? Not in the strong sense, but it seems almost tautological.

Is the goal an objective truth? Or is it a goal you subjectively assigned to yourself?

Your likes and dislikes about pizza are objectively true facts about you.

Subjectivism and realism are both cognitivist positions.  They both have an identical commitment to facts.  They differ in the point of reference for those facts.

If you wanted to argue against that commitment, competently, you would offer a non cognitivist objection.  That “good” in this context is not truth- alike. It’s nit something that even can be true or false.  It’s more like......”yum”.

I’m not really referring to facts about myself or facts about the pizza, just making a satisfied grunting sound in a complex way.

For the umpteenth time, learn the positions and terms.  Stop griping to me about how realism isn’t true.  It may not be, but to know what you’re disagreeing with you will have to learn the terms and positions.

Moral realism is based on some goal that you like, and assign to your self. I shouldn't do things that are bad for well being. This is fact about you, just like taste is a fact about me. 

It's like the goal I have to go to the gym everyday. Even though most days I don't want to, and I only manage to go once every six months.

Do you think the goal that I should avoid things that are bad for wellbeing, is an objective truth?

If you don't than you're whole moral edifice is as subjective, as pizza taste realism. If you say moral realism isn't about the goal, then I can apply the same logic and insist that pizza taste realism isn't about my personal taste, by insisting that it's about facts about the pizza.
