Quote from : Why Does He Do That?: Inside the Minds of Angry and Controlling Men Book

The central attitudes driving Rambo are: Strength and aggressiveness are good; compassion and conflict resolution are bad. Anything that could be even remotely associated with homosexuality, including walking away from possible violence or showing any fear or grief, has to be avoided at any cost. Femaleness and femininity (which he associates with homosexuality) are inferior. Women are here to serve men and be protected by them. Men should never hit women, because it is unmanly to do so. However, exceptions to this rule can be made for my own partner if her behavior is bad enough. Men need to keep their women in line. You are a thing that belongs to me, akin to a trophy.
