Cassidy Lynn Campbell, the 16-year-old transgender student who was crowned homecoming queen on September 20, has joined the NOH8 Campaign.

The Huntington Beach, California Marina High School senior broke down crying when gold and blue balloons announced her as the winner during the school's homecoming football game.

“I think it really shows the progress of the times,” she told reporters afterwards.

But in a nearly 9-minute YouTube video posted the following day, Campbell said that some people reacted to her win with “negative and ignorant” remarks.

The NOH8 Campaign raises awareness and fund for LGBT rights causes. It started as a protest against passage of Proposition 8, California's now-ended gay marriage ban. Celebrities and everyday folks are photographed with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.
