Auldsoul,
That is rather inconsistent, for you are turning to the Greek word qeos. You would seem to want to be consistent. If you are going to refer to Christ in the Greek as "god" you should then relate how he is in Greek as "true." To argue based upon a bracketed addition of true in an English Bible does not justify your assertion and only shows that it is not a Scriptural distinction.
You may not realize it, but even in contrast to idols, they are not spoken of as "false gods" in the sense of Jehovah as the "true God." They are considered based upon him, where he is the model upon which they were created by their makers, for he is God of all. He is the archetype upon which they are designed and so even with the idols the comparison isn't entirely proper in any example that I have been able to find. In the NT and LXX it is always AHQINOS in every example that I can find.
As for Isaiah 45, you have removed that Scripture completely from context, for it refers clearly to the idols of the nation when in context, having no bearing on others. Would you just as well go into Exodus 20:8 and say we cannot have art by removing it from its context?
For Psalm 8:5, elohim does not mean angels. "Angels" is a rendering based upon the LXX and is by no means a *meaning* of Elohim. Please do not confuse application with meaning. Here it is applied to angels but the word itself does not mean it. Glosses will note the application to them, but Hebrew lexicons do not argue for that meaning.
In Exodus 7:1 you are right that Moses is not "God" but the LXX makes it very clear that he is "a god to Pharaoh." This not not merely metaphorical, but it describes a role that Moses held to him and a role that Aaron held.
And finally for Psa. 82:6, they indeed are not gods in the worship sense as idols are, but they are to be honored and respected, for they are gods because they have been given a position of authority by God. The sense varies, but it still does not change the fact that properly they are called gods.
So in contrast what you said, these ones are properly called gods. They are not false gods, but they are gods positively. Psa. 82:6 confirms this especially, for in parallel to being "gods" they are "sons of the most high," a positive expression.
I'm calling you out on this argument not because of what the Watchtower says, but because of what the Bible says, so if you're going to make an argument, a Watchtower quote is not going to phase me and it is not going to make your argument true or false. The fact is, the Biblical use of "true" with respects God in contrast to Jesus does not support the position that you are arguing for. One could argue *at most* that it is an implication, but in light of who it is applied to, that would be false.
