- I think you should ask Evangelical Christians if they consider other humans inferior otherwise why else do they try to "save" them from their inferiority.

- You should ask KKK/Neo Nazis if they consider Blacks inferior or superior?

- You should ask Chinese if they consider the mixed race Black singer (from the Chinese version of American Idol) inferior?

- Some Muslims consider non-muslims Kafir.

- Shia and Sunni consider each other inferior.

- Some muslim sects in Pakistan, and elsewhere, are considered non-muslims.

- Jews consider Palestinians, and vice versa, inferior.

And so on and so forth...

So, yes, those examples do apply.
