Poets and novelists use metaphors, a right hemispheric form of language. As an exercise, try to come up with the name of a significant male writer who wrote long dense tomes about religion and philosophy and who also was not a misogynist. Women are generally not as affected by the masculinizing tendencies of the written words because the brains of women are not nearly as sharply divided as the brains of men. Women in general do not as often as men express extremes. Women who write feminist polemical books tend to express themselves more in their masculine modes.
Belligerency appears to be a fairly universal human trait.

There is no evidence that Neolithic agricultural people ever fought organized wars. The roots of mayhem are complex but I feel that alphabet literacy has been an overlooked factor. Like the printing press, it duplicates type, and must be read.
