Thalmor believe Lorkhan tricked the other Aedra into giving up on the Aldmer's divinity, and therefore despise him and his creation: the Humans. They consider themselves to be the only perfect Mer. Over hundreds of generations they have bred themselves into a racially pure line from the Ayleids, even more pure than the cannibalistic Bosmers and are now almost identical to one another in appearance.

The Dominion is formed to supposedly "unite" all Elves and prove superiority over Humans, but obviously there are differences in political beliefs between them just like there are between the Nords and Imperials & Reachmen and Nords.
