Fortunately, DD and I had talked several times prior to that incident about how you can tell when someone is really ignorant because they will use sentences with the phrases "girls can't" or "girls don't" or "boys can't" or "boys don't" and she was then allowed to completely ignore whatever they said next as being their own misguided opinion. Yup, had the sexism talk with my 3 year old. Then again and again with new and expanded topics as she has grown.
I like this! I'm definitely going to have this talk with DS. We've already discussed the fallacy of "too young" (there are almost always other objective criteria that can be referenced logically, instead), but I hadn't thought of a good way to in innoculate against sexism. Thanks!
