A camera floating through a classroom past male and female students of various ethnicities as text on the screen asks, "Who in here is gay? Is it you? Does it matter?"

The closing caption says, "Take a stand against discrimination."

The ad is part of a series in partnership between MTV and GLSEN, the Gay Lesbian Straight Education Network, which represents youth, teachers and administrators in K-12 schools. It represents some of the negativity that students face in high school.

MTV has set the gold standard among all advertisers for the most ads that refer to the community, more than 17 since 1996, in addition to carrying numerous gay ads from other companies and running its own supportive gay-inclusive programming.
