The way me and my one partner operate is very... well science-y I guess? He's looking into psychology as a field. I'm already going into biology. For us (due to these backgrounds in science) the terms male and female have pretty specific objective definitions and pretty specific objective usages.

I'm gonna have to bow out of this part of the conversation here, then. The idea of objective science when it comes to these matters... it just doesn't work for me. It's not objective, as far as I'm concerned. The characteristics we decide are "male" and "female" are created by cissexist assumptions. It's still overly simplistic for the diversity of human bodies, and doesn't reflect the lived experiences of many people.

And I know you don't mean anything by it, and I think I'm responding more to the overwhelming number of times this "objective" science has been used against me and people like me than I am to you, which is why I kinda have to stop here.
