What's wrong with being partial to one's own group? The whole world operates this way. Are we trying to make normal behavior into something bad. Blacks living in black areas are partial. Whites living in white areas, granted that there is a large minority population around, is partial. Mexicans living among Mexican, even if culturally assimilated, is being partial.
Your Point?
I'm partial to Christianity, and I am not ashamed to say that.
