What bothers me is no one is reacting as if she's responding in a way she probably shouldn't. Even in kindergarten they taught us it's not okay to hit people cause they upset you. That still holds true when you're forty.
Watching this play out made me realize my offense is irrelevant. I brought it up before because I saw it like stepping on someone's foot. People don't mean to step on each other's foot, and if you point out they did, they'll probably be more careful not to do it in the future. But that changes behavior, not ideas. They might decide if what they said offended me then they shouldn't say it, but that doesn't open up the dialog necessary to change their minds.
So yep, while I'm sure I'll be offended again in the future, I'm resolved not to let it show.
