Compete or Cooperate?
He has drive to compete buried deep within and male dominance to back it up. When sensitive discussions with her shift toward confrontation, he shifts into competitive mode and then resorts to his dominant nature to squelch argument. This happens easily because, except for conquest, men naturally avoid competing directly with a woman.
She has cooperation embedded in her need for brighter future. Unfortunately, taught by feminists to disrespect the male gender, she shifts sensitive discussion toward confrontation. This energizes his competitive spirit followed by dominance in order not to win so much as to squelch dissent or argument. Men just don’t wilt under competitive pressures, especially in front of someone they can otherwise dominate. She lost when she chose confrontation over cooperation.
