focussing on the present adults' daughters' futures would probably be the most emotive way to grab womens' attention and motivate them.

since women are definitely doing the most double-dutying and spending quality time with their kids, ask them whether they want another generation in the same pickle.

using that poster from 1954 and captioning it with that message would be quite powerful, i think.

good luck with this, gender injustice demeans women,  and demeans men even more.
