Inconsistency

Does the Rabbi also believe this about someone whose opinion is reasoned regarding his position that morality is binding regardless of God, even if the Rabbi thinks he is wrong?

For example, I, although I believe in God, nevertheless believe that morality is binding regardless of God (and cannot be binding solely because of God), as I discussed with the Rabbi in the past regarding this:

And as the Rabbi can see in the thread, even though the Rabbi does not agree with this position of mine – my opinion is reasoned and I arrived at it after thinking. Therefore, even if I am wrong as the Rabbi believes, does the Rabbi necessarily think that in fact, unconsciously, I also believe, as the Rabbi believes, that morality is binding solely because it is the will of God?

Or in other words: An atheist who holds my position regarding morality, does the Rabbi also believe that there is an inconsistency in his position, or does the Rabbi think that he is simply wrong but that there is no inconsistency because he has a reasoned explanation (wrong, in the Rabbi's view) why morality is binding despite his lack of belief in God?

[P.S. – I would be happy if the Rabbi could respond to my latest claims in the above thread]

I don't understand the question. If you hold two contradictory principles, you are inconsistent. The fact that you think they are not contradictory only means that you are not aware of your inconsistency.
