I've heard a lot of weird things claims about what "makes" people gay.
The list has included a lack of sports, certain TV shows and movies, distant fathers, distant mothers, overly close fathers, overly close mothers, sexual abuse, physical abuse, emotional abuse, no discipline, sexual curiosity and experimentation, overly strict religious upbringing, overly lax religious upbringing, genetics, environment, the erosion of traditional gender roles, exposure to Broadway music, participation in ballet, being a sensitive artistic sort, leg hair, and lack of friendships growing up.
Never have I heard someone pin it on diet. Until now.
Apparently, America's growing desire for health food is turning us into a soy bean Sodom.
You just can't make this stuff up.
