No, they're not sexual deviants. Someone can be depressed about making chicken all day but still make good chicken, someone can have OCD and make the best chicken ever because it has to be "just right" in order to serve it, someone who questions thier own identity and associates with like minded people, having sex as one gender one night then another on another night is much more highly likely to be a walking bacteria factory. It is well known just how "dirty" homosexual sex is, and why more often than not two people in a monogamous heterosexual relationship have nothing to worry about, as long as the carrier cook at McYuck doesnt cut thier finger and bleed it all into thier burgers.
