George Takei and Jennifer Tyrrell protested the Boy Scouts of America's policy banning openly gay scouts and leaders at Sunday's 43rd annual New York City Gay Pride Parade.

Takei and Tyrrell waved at an estimated crowd of 1.5 million revelers from the back seat of a red Ford Mustang convertible.

Tyrrell is the 32-year-old Ohio mom who in April was ousted as den leader of her son's Boy Scout troop because she is a lesbian. She launched the petition to bring awareness of the Boy Scouts' policy banning openly gay scouts and leaders. The petition has attracted nearly 300,000 electronic signatures.

“Some of my best memories from my boyhood are of my scouting days,” Takei said in a statement released by GLAAD. “I played bass bugle in our troop's drum and bugle corps. We marched in Fourth of July parades. We learned teamwork and brotherhood from camping together. The Boy Scouts built my character. As an adult, I was shocked and deeply disappointed to learn that the Scouts discriminate against LGBT people. This is contrary to the ideals of equality and fair play that I hold dear. The Boy Scouts must change.”

A resolution which would allow individual charter organizations to decide for themselves whether to accept openly gay members and leaders was introduced last month after Tyrrell's petition was delivered.
