The whole gay thing doesn't even matter to me. What matters to me is what can you offer the tribe? Medical, politics, intel, engineering, growing food, food storage, getting water, storage of water, firearms, training, ect. ect. ect. That's what matters to me. Can this person help our tribe, pull their own weight, and help us survive in some valuable way. That's the same question I would ask anyone before letting anyone in my tribe, no matter race, religion, sexual orientation, whatever. I would hold everyone to the same standard, just as I do now.
If I just thought anyone, gay or straight, was a completely useless human being and could only add negatives and knew nothing about our operations I'd either send them on their way. or they could make useful fuel.
