Just PLEASE avoid what we were taught as kids, that boys have tenderly fragile egos so a girl has to pretend to know less and be less capable. We are all imbedded in culture and that was the “solution” that the U.S. culture of the 1950s and 1960s advised. Of course, doing so only strengthened the arguments against females advancing and further injured females into another generation. So, we are where we are today where the ERA HAS been ratified by over 3/4 of the states but Mitch McConnell is refusing to let it come to the floor for completion. (Remember that the last ratified Amendment before this, Amendment XXVII, Congressional Compensation, took over 200 years to get enough states to sign on, 1789 to 1992.)
In this case that same self-denial has been imposed on people of color so that also has to be considered. A late friend, Mary, used to tell me how in the Southern states where she lived when young that behavior was a way to avoid becoming a victim of violence, so people were forced to participate in undermining themselves to remain alive.
I am sure, though, that there are still some who advise such approaches, because culture is like the soles of our shoes, and what we walk through in life does get stuck to them.
