> The coworker in question is a heterosexual white male. My manager is a heterosexual white male. There are five other people in my organization in the office where I work. They are all heterosexual white males. How is this person so sure of this? I have no idea what the orientation of anyone I work with is... I can eliminate "homosexual" or "heterosexual" for most of them, as they have mentioned ____friends, but certainly cannot eliminate "bisexual"...
