Shep is no different than any other homosexual. Their "sexual orientation" is their identity -- period. That is all there is to them. They view the world through a prism of homosexuality. That's why you hear them talk incessantly about being gay, or what it was like growing up gay, or what it was like being in the closet, or when they first realized they were gay. EVERYTHING is about their sexuality.
Not unlike the BLM crowd, where everything is about RACE.
