For example:
"One day, one of my supervisors jumped to my defense at a team event, in an awkward display of sexism."
I'm sure there's a way that a supervisor jumping to your defense could be sexist, but this isn't showing that, at all.
"At a lunch with several other coworkers, one of these men ordered me to summon the waiter and pay the bill, in the tone of a command to someone inferior and subservient."
Certainly odd behavior, but I'm not sure I would call it sexist. Arrogant for sure, but surely there's more context?
To be clear, I'm not saying she's wrong, just that this story isn't helping me understand what she went through, or that it was particularly sexist, versus just hostile.
