I'm looking for a sutta which mentions nationalism

I remember a sutta which uses the word "nationalism" in reference to a taint to be removed. It was the last in a certain sequence of taints. I think i read it on access to insight. However, when i search for the word i can't find any such sutta in either dhamma talks or access to insight. Or anywhere else for that matter. Can someone \*ahem* enlighten me?
