"dry dorms are for asians"

Last week, a substance-free dorm at Princeton University was vandalized with graffiti characterizing its residents as "gay" or "Asian": Graffiti found in Blair Hall. The graffiti, written on a whiteboard and a wall in blue dry-erase marker, read "Dry Dorms = Gay" and "Dry dorms are for Asians." That's racist! And you know why? It equates Asians with inherently being undesirable losers. Because it definitely doesn't intend to mean "Dry dorms are for cool people." And just out of curiosity, since when did being "Asian" equate with avoiding alcohol? From what I've seen, Asians drink. And Asians drink a lot.
