It was over a potluck dinner—maybe the time he’d whipped up a quiche and his mom’s special chocolate dessert for the regular gathering of college classmates—that University of Puget Sound psychologist Donn Marshall “heard the call.”

He was young, still a student, and for the first time someone he greatly respected had questioned just who Donn was and where he fit into the world. It was the ’70s, when the women’s liberation and gay rights movements had captured the national stage. While Donn empathized strongly with those rallying cries, he says that as a straight white male, he was “clueless” about the role he could play.
