see racism in 40K is like; Necrons think you're primitive, Tau think you're CHARMINGLY primitive, humans think you're scarily anathema, and Aeldari think you're loud and declasse, which is something coming from the species which invented Glam Rock millenia before everyone else. Orks think you're punchable and edible, but they think everyone's punchable and edible, similarly to how the Drukhari are very open minded about torture victims.
