Psychology is called a Pusdo-Science for a reason, because it's not conclusive and nothing can ever be 100% proven.
Okay, I take exception to this. You may not agree with some psychological conclusions, but it is definitely NOT a pseudo-science. It is a social science, a category of studies which have a very different structure than the physical sciences. Also, a lot of things in psychology CAN be proven for a general audience. Social sciences focus on large groups, for which they can be very specific. With individuals they sometimes have troubles, however.
Men and women are VERY different. This, I believe, is part of what interests us in each other. Men are more aggressive/violent. This is not just socialization, this is a pattern of behavior proven by countless societies and countless peoples on the earth.
Pointing out that you know exceptions to this rule is an invalid argument when speaking of the social sciences, since--as stated above--they deal in generalities. In general, men are more aggressive, more visual, and more physically confrontational than women. We have chemicals inside of us that produce certain effects on our bodies--it's not just in our heads.
