Formal debates arefortwo people... what about the rest of us?
The fine-tuned argument is a challenge to non-theists to come up with an alternative to 'Goddidit'. Anyone who wants to refute 'goddit' has two options a) deny the universe is fine-tuned or b) concede the universe is fine tuned, but not by the gods.
a) involves appeal to the anthropic principle/puddle argument. b) involves an appeal to the hope that future discoveries will reveal a non-supernatural reason why the physical constantsre as they are.
it's all very unfair, because the 'goddidit' crowd get away with just claiming 'godfinetunedit' with no furter detail but insist refuters cross every t and dot every i!
i'm not keen on appeals to the AP, but until/unless a postive theory that explains the value of the physical constants turns up the AP will have to suffice!
