A secret poker game you can play on the subway

I prefer not to play a game that requires assuming anyone's gender or age

But its a cute idea

Aw I feel like it’s perfectly harmless in this instance, right? You don’t need to talk to the people, so there’s no risk of insulting them.

Agreed, but you risk normalizing it for yourself, and the partner playing it with you.

I don't think it's particularly harmful for someone to play it, but I would rather set the bar higher for myself.
