As I edited in my previous post, I see these societal pressures as present, but currently not very influential.

As for why we're arguing, miscommunication. We both though each others positions were more exclusionary than they actually were (I thought you fully poo-pooed biology, you thought I fully poo-pooed societal pressures).

But, through the magic of discussion and perseverance, we've battled past all this ego and lingual fog to reach a mutual understanding and acceptance.

Glory to communication!
