Recently, when Constance McMillen, an 18-year-old senior at Itawamba Agricultural High School in Jackson, Mississippi, challenged a long-standing school policy that barred her from bringing along her girlfriend as her prom date (not to mention wearing a tuxedo), the school responded by canceling prom altogether.
McMillen's response: "That's really messed up because the message they are sending is that if they have to let gay people go to prom that they are not going to have one. A bunch of kids at school are really going to hate me for this."
And while on the topic of perception-shifting, despite having lost her bid for the White House The New York Times' Gail Collins is fond of describing Hillary Clinton's loss as having achieved something equally important: "She got the country used to the idea. It seems normal to us now."
Maybe McMillen's fight to take her girlfriend to prom is but the latest hurdle.
