Did you miss the part where Dahmer “had sex with his male victims before killing them”? No, that doesn’t mean he has a homosexually twisted view of sex at all, or why he was so conflicted internally. Nothing to see here. Just another perfectly happy member of the pumpkin patch.
You're still ignoring that the essay you cited is contradictory to the entire concept of LGBTQ+ being a "choice" that you are professing. And no, we don't say rapists and pedophiles and sexual abuser are "straight' based on their victims sex and sexuality. That's not how that works.
