Whether he is disdainful should be judged by what Odysseus says and do. Not by what goddess do.

In the story Odysseus is not behaving in disdainful way to gods at all. He is not disrespectful, he is not treating gods as unworthy. It quite the opposite the whole time.

I will add that his respect towards gods is something Athena brings up at one point as argument towards other gods and argument works. Odysseus gets help. For that matter, Odysseus gets a lot of godly help.

There is one god that is angry with him trying to kill him (cause Odysseus killed his son without knowing it is gods son) and one that keeps him trapped on island cause she likes his presence. Odysseus never express disdain toward her through nor toward gods in general.

I accept your correction. Still, Odysseus clearly doesn't like being held as a sex slave by not one but two different goddesses.

Imo, his situation was considerably better then the one of slaves. He was kept not allowed to leave and yes he had sex he did not wanted aka rape.

But not every prisoner is slave. The slaves are present in the books.

Slaves are also killed by Odysseus himself if they had sex with suitors, no regard is made to whether sex was voluntary and odysseus himself claims that sex was rape before (but he just guesses that).

It is not like that story took much regards with regards of rape.

How does "holy moly" relate to the Odyssey?

Moly was the sacred herb that freed Odysseus from Circe’s spell.
