"Of course her gender matters". Your quote. If you are in a supervisory position I wish I could provide this quote to your male subordinates if they are ever dissatisfied with their ratings or promotions.
What "firsts" are worth extolling for a CNO at the POTUS level? Let's see: Black, Hispanic, Lesbian, Gay, male-to-female-trans, female-to-male trans, male-to-female-back-to-male-again trans, Muslim, Jewish, Asian, etc, etc, etc, etc. When you do the math there are limitless combinations. So how about we just assure the American people the best qualified are being chosen to protect our nation and lead our children into harm's way instead of making important appointments sound like it's done to appease a bunch of campus protesters?
