They have campaigns for everything now

==================
Homophobic remarks such as “that’s so gay” are the most commonly heard; these slurs are often unintentional and a common part of teens’ vernacular. Most do not recognize the consequences, but the casual use of this language often carries over into more overt harassment.

This campaign aims to raise awareness about the prevalence and consequences of anti-LGBT bias and behavior in America’s schools. Ultimately, the goal is to reduce and prevent the use of homophobic language in an effort to create a more positive environment for LGBT teens. The campaign also aims to reach adults, including school personnel and parents; their support of this message is crucial to the success of efforts to change behavior.
==================
They even have commercials with Wanda Sykes and Hillary Duff
