I place no moral judgments on either, nor do I claim this evolutionary link is certain by any means. Just that both are useful in different contexts, and in the modern world where sexual intercourse isn’t required for procreation, we have the freedom to choose.
No moral judgements here either, I'm just someone very interested in evolution of human species. I only attacked the 'appeal to Nature' fallacy which is otherwise most commonly used against lgbt people.
The only appeal to nature I make is that humans are incredibly diverse. Monogamy is a default state for some human beings; as is polyamory for others. And there are likely a lot of people in between who would be open to either in the right context.
