Mr. Schneier’s eldest child agreed. “This is a small oasis of something hopeful amidst everything that’s happening politically,” said Tal Bogomolny, 20. “It’s been really special to witness. Seeing a parent finally settle into themselves is very meaningful. They both feel so safe with each other. It’s uplifting.”

At 7:40 p.m., a gluten-free, triple-layer cake was cut. The bride and groom fed each other. A bouquet of white freesia was tossed, and caught. Willie Nelson crooned “Love Is Here To Stay” as the pair danced for the first time as a married couple.

As the sun set, guests started to leave. The trucks stopped serving food; two women who sang bluegrass packed up. Remaining guests milled about; others joined the couple who were still dancing on the deck.

“Both of us are bisexual, and yet it’s the straightest relationship I’ve been in,” Mr. Schneier said. “If Allie stayed a man, none of it would matter. It’s about the person I fell in love with. I feel a tenderness toward her I haven’t felt toward anyone else.”

Ms. Brashears uttered similar sentiments. “Love is finding the person who understands you more intimately than you ever thought possible,” she said. “He looks very different than he did two years ago, but it hasn’t changed who that person is inside and who I talk to. It would have been overwhelming not to have had each other.”
