This is why I've come to view group-identity and banners as what's wrong with the world (the word 'granfalloon' has never been more relevant, yet somehow it's never made it into the common parlance, even as a "controversial" thing!): They can be counted upon to goosh together those that have no business being "on the same side", AND they divide those who should be, to boot!
