One of the nation’s first openly gay Eagle Scouts has a message for Amazon: Stop supporting an organization that discriminates.

Pascal Tessier, a 17-year-old from Chevy Chase, Md., who made history when he received the Boy Scouts’ highest ranking earlier this year, held a news conference Monday in front of Amazon.com’s office in Northwest Washington. At the event, he announced his intent to deliver more than 120,000 signatures to the company’s Seattle office in an effort to encourage the online retailer to drop the Boy Scouts from the list of organizations that can benefit from its charitable program, AmazonSmile.

Tessier’s effort comes after the Boy Scouts kicked out Geoff McGrath, an openly gay scoutmaster in Seattle. Tessier, a senior at Bethesda-Chevy Chase High School, put his Eagle Scout rank on the line last year when he spoke to the media about being gay and participated in a public demonstration in advance of a vote held by the National Council of the Boy Scouts of America to determine whether to lift a long-standing ban on gay members and leaders. Ultimately, the council voted to accept gay youths but not gay adults.

Tessier said what happened to McGrath confirmed for him that his time with the organization is limited — unless change occurs.

“It kind of re-ignited the feeling of anxiety and fear,” he said. “It proved they are still going to punish adults, so when I do turn 18, now I know for a fact I will get kicked out.”

His birthday is in August.

Deron Smith, director of communications for the Boy Scouts of America, cited a previous statement on the issue in response to Tessier: “Scouting represents millions of youth and adult members in diverse communities across the nation, many who have a variety of beliefs on a number of topics. We fully understand and appreciate that not everyone will agree with any one position or policy. America’s youth need Scouting, and by continuing to focus on the goals that unite us we continue to accomplish incredible things for young people and the communities we serve. “

A spokesman for Amazon said in response to the protest that customers can select from nearly a million legally recognized charitable organizations on AmazonSmile. “We rely on lists published by the Southern Poverty Law Center and the U.S. Office of Foreign Assets Control to determine if certain organizations are ineligible to participate,” Ty Rogers said.

Tessier said he started gathering signatures through Change.org after learning that the policy for AmazonSmile prohibits organizations that “engage in, support, encourage, or promote: intolerance, discrimination or discriminatory practices based on race, sex, religion, nationality, disability, sexual orientation, or age.”

“We’re just asking Amazon to stand by its own policy, and its commitment to the LGBT community,” Tessier said.

On Wednesday, Tessier plans to travel to Seattle to formally petition Amazon.com and its founder and chief executive Jeffrey P. Bezos, who also owns The Washington Post.

Tessier said after he graduates from high school he plans to attend college in Ohio. He hopes to continue participating in Boy Scouts — but he’s aware of the reality.

“The likelihood of that happening is very slim,” he said, “because there is so little time to change so many minds.”
