You speak about people reflexively picking their teams. But what about people that reflexively put everyone they meet on teams?

I hold no allegiance to Team Testosterone but, if everyone who sees me says, “oh, yeah, you’re Team Testosterone. And also I know everything I need to know about you now.” It gets a bit grating.

It is safer for vulnerable people to make those assumptions and I won’t begrudge them their safety. But I don’t have to like how it invalidates the lifetime of interactions I’ve had and I won’t feel compelled to laugh when a offhand joke necessarily implicates me because of the team I’ve been assigned to.
