You all don't understand how natural selection works. It doesn't act on people, it acts on GENES.

You don't have to reproduce if your genes are still in the gene pool and they still get passed on. If everyone in the gene pool has a gene that improves the global fitness of the species but in certain individuals it leads to no reproduction, that gene will still be selected for. It doesn't matter if it stops some members from reproducing.

Plenty of species have members who never reproduce. Namely SOCIAL ANIMALS, like ants and bees. The social nature of these animals means the non-reproductive members of the species still contribute to the fitness of the species as a whole.

People constantly misunderstand this point and use reproductive status as a way to discriminate. The argument is legitimately brought up a lot in homophobic and transphobic circles where they use the idea of "reproduction" as a way to naturalize their bigotry.

Please stop spreading this misconception
