How to easily defeat any argument for God

[Belacqua]

My view rejects a common conception of God, at least among atheists , where morality is some set of arbitrary rules from God, it rejects the sort of idea of god, that makes things such as the  Euthyphro dilemma possible,  in favor of a conception of God that falls in line with Plato’s conception of the Good.

There seems to be a disconnect here, that is very difficult to get past.

The God that most anti-religion people argue against is very anthropomorphic. It is a reacting, changing guy who lays down laws. What Blake called "Nobodaddy." 

I'm not sure how we can impress on people that for Christian philosophers, this has never been the case. What you are stating here is a widely-held view that, while maybe not known at the church on the corner, is nonetheless deeply embedded in Christian theology.

Maybe it would help to define the word "good."

I'll posit that a good thing is one that satisfies human desires, and brings happiness.

It is subjective, in that individuals (subjects) interpret whether the thing will make them happy or not. It is also objective, in that the object may or may not actually satisfy desires.
