True, IMO, though this is itself not really an objective fact.
2. There are objective moral values and duties.
Well, I believe there are, but this statement is not a fact, it is a statement of belief. It cannot be proven in the same way a mathematical theorem can.
3. Therefore, God exists.
Anybody convinced by this argument knows nothing of logic. Both of the premises are statements of opinion, not fact. Only someone who already believes them will be convinced that the proposition is true.
To be clear, I agree, but it is a really poor argument to present to someone who doesn't.
But since FACTs tend to show that more people are influenced by opinion than fact anyway; then percentage wise, it is a good argument.
Got that right.
