I don’t care if you are straight, gay, lesbian, bisexual, pansexual, omnisexual, polysexual, queer, questioning, fluid, asexual, demisexual, heteroflexible, homoflexible, or other. I don’t care if you are the biggest human rights supporter ever, have only the best intentions, thought it would be fine, or if you are a magical talking centipede.
Outing other people without their express permission is not okay. Ever. End of story.
