There is absolutely no reason to bring race into it. If you need to tell someone to be more assertive, then tell them to be more assertive and give examples of how and explain why. Don't bring up racist generalizations and hope they are interrupted the way you want them to be.
Saying that white men are confident and black women aren't is simultaneous bi-directional racism. You are generalizing white men and black women AND telling black women to act more white?
