People feel more comfortable with those of commonality. It's the lure of shared values. It's why lesbians flock to IU women's basketball games, successful white people converge on Carmel, East Indians reside together in huge neighborhoods on the west side of Columbus, IN and why Chicago has its Little Italy and Polish neighborhoods. It starts at the quantum world of sub atomic particles, all the way up to commonality of universes in hypothesized universal clusters...probably. Whatever it is, is okay, for it doesn't mean one is racist for supporting one particular group in favor over another. Cheer louder for Jordy Hulls when it comes naturally.
