Amazon, the world's largest online retailer, is being asked to withdraw its support of the Boy Scouts of America (BSA) over the group's policy banning opening gay leaders.

While the BSA ended its ban on openly gay scouts in January, anyone over 18 who is gay may not participate in the organization.

Last week, the policy forced out Scoutmaster Geoff McGrath, prompting Pascal Tessier, considered the country's first openly gay Eagle Scout, to ask Amazon to end its support of the BSA.

“The Boy Scouts of America just fired Scoutmaster Geoff McGrath for being gay,” Tessier, who is 17, wrote in a petition that has accumulated nearly 30,000 signatures in just 2 days. “Despite that, Amazon continues to support the BSA through its Amazon Smiles program. Geoff is an Eagle Scout, a husband and the founder of two Scouting units in underserved neighborhoods.”

“By removing Geoff, the BSA is depriving the youth in these units of the opportunity to be a Scout and they are telling all their youth that discrimination is okay.”

“That's a harmful message for all youth,” Tessier concluded, “gay and straight alike and it has no place in Scouting.”
