Jennifer Tyrrell, the former Tiger Cub den leader dismissed because she's lesbian, said Wednesday she'll campaign for the Boy Scouts of America (BSA) to accept gay leaders and scouts.

Last month, the Boy Scouts removed Tyrrell from her volunteer position, telling her that her sexuality did not meet the group's high standards of conduct.

Tyrrell's 7-year-old son Cruz has since dropped out of his troop.

“We can no longer support an organization that has these policies and we hope to get them changed,” Tyrrell told ABCNews.com. “That is our main goal.”

“But Cruz is a little sad,” she added. “We loved scouting.”

The 32-year-old Ohio mother has launched a Change.org campaign to bring awareness of the policy.

“I had no idea this would take off like this,” Tyrrell said, referring to the nearly 150,000 signatures the petition has received. “It's humbling and very exciting that so many people are finally agreeing with us.”

The Boy Scouts of America on Wednesday reiterated its opposition to gay leaders and scouts.

“Scouting, and the majority of parents it serves, does not believe it is the right forum for children to become aware of the issue of sexual orientation, or engage in discussions about being gay,” the group said in a statement. “Rather, such complex matters should be discussed with parents, caregivers, or spiritual advisers, at the appropriate time and in the right setting.”

During an appearance on CNN, Tyrrell conceded that she was aware of the group's policy but was assured her sexual orientation would not be an issue. (The video is embedded in the right panel of this page. Visit our video library for more videos.)
