Concerning your first argument: Humans are social (just like gorillas and chimps), so a human female will be protected by her group, and in more recent culture,her father and brother. Additionally human females can defend themselves or run away roughly as well as a man, just like any female organisms that is sufficiently similar to their male counterpart. A female needs a mate to protect her only when she is pregnant because she becomes almost completely defenseless and needs more constant protection than a group or large family can provide.
For the second point, the main consensus with evolutionary anthropologists it that male drive to stay with their mate comes from three factors: a female with usually only mate with a male if she knows he will stay (sexual selection), a male's offspring will be more likely to survive if he protects them, in a tight-knit community a male would face social difficulties if he refused to care for his children against the female's wishes forcing him to leave and not likely survive alone. In my opinion humans are too complicated of animals to sum it ALL up to evolution, men and women can love each other because are brains are just so complicated we don't only equate our mates to sex. I disagree that "any woman who won't sleep with a man PURELY for visual reasons is a product of society" because by nature, women look for loyalty, intelligence, and gentility as well.
I believe only the specifics of how women choose a mate is up to society. As a last note: men are very similar to women, and sex (pun intended) is about the only place the differ,but only slightly. Also, even though I disagree a bit, I thought your argument was quite strong and well-reasoned.
Size and Strength matter when a saber tooth tiger "keeps coming". Emplace a spear butt on the ground held by a foot and set to receive a charge by 1000 pounds of ferocity with only a sharpened shaped rock on a length of wood to stop it before it eats you. UNDENIABLY, size and strength mattered... EQUALLY, fire on the end of a stick would keep the tiger from charging.
SO, NOW the "firemaster" has equal protection capacity as the tribes largest "hunter"... "protection" ability, if not the ability to clothe her in a tiger skin afterward or to wear a really nifty tiger fang necklace. Sooo.... "evolutionarily" "ability" (brains) has mattered as much as bulk for a LOOONG time. Long enough that females insistence on "big bad boys" STILL is worthy of some scorn, especially by well educated little guys.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
