Genestealers are not an argument they would be using if they had ever read, well, anything about them.
As a creature they are literally miscegenation incarnate. They infiltrate areas and corrupt humanity down to the genetic level. The offspring of people infected by genestealers become a fucked up mutant inbreeding cult the likes of which Lovecraft could have thought up. And they do this until they have built up enough numbers to overthrow society.
Genestealers are literally 40k's argument against race mixing.
