If the U.S will ever replace the male figures of past U.S notables of National leadership roles to Country and Society to females, the U.S will also be changing its Patriarchal system of Government and family to a Matriarchal system. Although the female pictures can be a warm feeling of having and holding proper respects towards women, it could also be a way for male leadership quality skills to begin to decline. And the question of why women are in any way being held in disrespect should be kept on the serious level since there might actually be those who sincerely feel attacks to their birth gender. Otherwise, it would not be so much about 'inequalty' per se, but more about 'monetary/responsibility' in the work force, equality/inequality.
So if a man puts a dollar in his front pocket and it has a picture of a woman on it wouldn't the left consider that sexual assault since he is putting her face close to his penis?
