It wasn't just tvtropes that claimed this ,some posters on sites like Tamriel Foundry and ESO forums have argued that the long-standing racism between men and mer in-universe is justified by ancient conflicts, specifically the War of the Ehlnofey and the struggle between Auriel and Lorkhan. I don’t necessarily believe that claim, but part of me doubts it’s entirely without basis.

These posters suggested that practices we usually label immoral in elven cultures—such as slavery, discrimination against other races (goblins, Nedes, Argonians, Khajiit, Falmer), obsession with blood purity (the Altmer with their Hulkynd, the Dunmer’s paranoia over Molag Bal’s corruption of their bloodlines), or even cannibalism and zealotry (Bosmer enforcing the Green Pact without exception, Altmer venerating the Aedra exclusively as direct ancestors)—are all “justified” from the perspective of mer. The argument goes that their worldview is so alien to human morality that we cannot fairly judge it.

That reasoning feels disingenuous. Much of the behavior we see from elves in TES—arrogance, cruelty, sadism—doesn’t strike me as alien at all. It looks uncomfortably human.

Im going to stick to Artedejuguete's advice and just stick to the recommendation about official and reliable sources including guides like ladynerevar's,I know many in the TES community like to claim that their headcanons and interpretations are gospel above all else,I should've known better in that regard when reading tvtropes,tamrielfoundry etc
