I think the author clearly addresses this: > When I’m able I’d much rather spend the time to educate someone about diversity and inclusion issues and see if I can change how they see the world a bit. But I don’t always have the time and energy to do that. And sometimes, even if I did have the time, the person involved doesn’t want to be educated. I don't think the author is suggesting that every cultural faux pas should be met with "We don't do that here." She's suggesting it for a certain use-case.
