I think they are taught this by a culture of devaluing women, desensitization to violence and objectification, etc. People in the middle and low ends of the bell curve of IQ cannot figure out the media/corporate manipulation for themselves--it's too subtle for them--so they keep on believing penis people are kings and females are inferior and deserve to be disrespected.
I think too, that many women have helped accentuate this. If women as a group would rise up and realize that we have the power, the world would be a better place.
You know what I say, I say screw the penis people
Once or twice a day at least.
