The LO wiki says “according to Hades, Demeter would often argue with him about anything and he found it difficult trying to get along with her. It is also the main reason he never tried courting her back in their youth.”

This scene is meant to be an "ohh, so that's why Demeter hates Hades!" moment, but really it just comes across as one more reason for her to hate him.

Consider the fact that Demeter seems to just distrust/hate men in general. I mean for god's sakes, she chose to raise her daughter in the Mortal Realm among a tribe of women literally hand picked into existence (through botany lol) rather than in Olympus where there is both gender-diversity as well as a wrathful manipulative male God running ...

Why does Demeter hate Hades? Demeter's dislike for Hades stems from his abduction of her beloved daughter, Persephone, causing Demeter immense grief and the earth to suffer. What colour is Demeter's hair?

Hades’ motivations stem from his loneliness and the need for a companion in the shadowy depths of the Underworld. However, this act of abduction triggers a monumental response from Demeter. Demeter’s grief upon losing her daughter plunges the earth into a barren state.
