I think Groups often Dehumanize the Other.
In fact, anytime Greek culture represented men with a large phallus, they were either monsters, barbarians or rapists. Deeply inhabited by an animalistic nature.

Also the Romans towards outsiders later on,
Gauls, Celts, and 'whatever 'Others they were fighting, I'd imagine.
I'm sure there is often a dualism, claim the Other is some brute animal, only capable of physical work, driven by animal instincts.
But some people also like manly primitive violence at times.
Try to have their cake and eat it too.

Look at Africa or Europe, doesn't 'need to be another color.

Ethnic Pygmy populations in Central Africa have suffered from racialized discrimination from Bantu peoples.[1] They are frequently ostracized from participation in wider society in the various African countries that they live in and are seen as untouchables.[1] Racially-motivated attacks have occurred on Pygmies including rape and cannibalization.[2][3]

Historically, the Shanqella constituted most of the slave labour in the ruling local Afro-Asiatic societies.[20] The Abyssinians (Habesha highlanders) were also noted as having actively hunted the Shanqella during the 19th century.[21] Following the abolition of the slave trade in the 1940s, the freed Shanqella and barya were typically employed as unskilled labour.[20] Racial discrimination against the barya or Shanqella communities in Ethiopia still exists, affecting access to political and social opportunities and resources.[18]
