Discrimination not only comes from 'feeling superior to' but also  'being other than'.

It's tribal in its core - 'They' could be the exact same race, following the same gods, but they are 'other' - 'not us'!

This separation, potentially originally value free even, leads to segregation, that makes it foreign/alien. Then add fear of the unknown/unfamiliar, fight for or access to resources, greed, envy or plain power hunger and you get a common target to dicriminate to make 'us' feel better.

If you aren't better than the others, then the others must be worse.
