The campaign stems from a partnership between Gay and Lesbian Alliance Against Defamation and the American Federation of Teachers.

The PSAs are being launched the week before Oct. 20's Spirit Day, the annual occasion when Americans are asked to wear purple to show support for lesbian/gay/bisexual/transgender youth.
