From an interview with actor Mark Ruffalo promoting "The Kids Are All Right," in which his character attracts Julianne Moore's character, the femme in a butch-femme lesbian household, into a heterosexual affair:
... Ruffalo says he has come up against some bizarre territory marking and paranoia in the real world as a result of the movie.
"I was doing an interview with a woman on tv and afterward the woman said, 'By the way, I'm a lesbian, and you lay off our women,'" Ruffalo recalls.
"At first I thought she was kidding and then I realized she was really serious," he adds. "She totally meant it. I was like, 'Are you kidding?'"
Ruffalo worried "she was going to arm wrestle me or something." He didn't think he'd fare well either: "Not against that passion."
