Normie gender discussion

I ask that myself whenever I witness people trying to figure out "who's the man" in a lesbian couple, or "who's the girl" in a male couple or "what bathroom will they use" whenever they're slightly confused with what they see. Seems to be a complicated job to be perfectly normal.

This is the data sets I live for..

This is really weird. How do people have this much energy to even think through all this crap.
