Holy **** this thread killing me rn.
First, we need to think about the scientific logic of this proposition; if evolution favoured this system of reproduction, humans would essentially be hermaphroditic and, therefore, there would essentially be zero gender barriers (or at least zero need for one). Male/female sexual reproduction has evolved specifically to provide the kind of genetic diversity to sustain populations. The idea isn't entirely feasible, but I would suppose that in this situation homosexuality would
have to be more acceptable; it's a natural method of reproduction. It would be a more or less "normal" thing and grounds for sexual competition and a way of transmitting genetic information and would thus be more common. This is just a scientific hypothesis though with zero social implications, I hope nobody is offended by what I'm saying.
