How lowly do Eldar think of humans in a general sense?

I'm doing some writing and from what I can notice in most Black Library material Eldar in books (majorily non-Eldar books even if they act like this in their own books) as EXTREMELY arrogant and haughty even in civil environments.

To the point that you got stuff like Godblight where Illiyan outright says he cannot stand being near humans from the way they sweat, smell, move etc or the many infamous incidents in 40k games where whenever Eldar appear they always need to act like mustache twirling villains and go "NO HUMAN DONT DO THIS" and insult the Imperials (humans are dumb i get it) and cause another disaster due to it as the writers in any format go out of their way to make Eldar fit hard into the Arrogant Racist Elf trope.

This of course as most people know have caused a majority of people to just hate Craftworld Eldar without even knowing their lore or what they do half the time and toss them into the "arrogant asshole elf" box even though you could argue most Imperials or other alien factions like Necrons abundantly surpass Eldar when it comes to the gall and arrogance department etc etc.

What I want to know is going back to the title; is it fitting for Eldar to act this way all the time with humans even under diplomatic surroundings or is there just no other way around this trope?
