This woman is giving you a thumbs up. IS THIS FEMINIST?
TRIGGER WARNING. The “thumbs up” is the most phallocentric gesture imaginable. You are literally telling someone that a good job is the equivalent of growing a penis. In this case, two penises.
Additionally, this kind of casual congratulation has been known to put the recipient in a good mood, which can lead to entire minutes of complacency about their own privilege. PROBLEMATIC.
