You do realize that when you put together the two points you made :
In a fight for your life kind of world, women are at an extreme disadvantage (individually). Men are stronger. Men can provide for themselves, even with no support.
and
Men said they would date 80% of the those pictured. Women said they would date 20% of those pictured.
together they make the point that women are completely justified in being very particular in trying to pick the the right man for her future needs as they (the women) are going to pay a high price if they choose badly. Many men seem to resent that women are so choosy if a woman decides on meeting him that another man might better suit her future needs. You don't end up married to the guys you don't date.
I would agree with you, accept for math.
Sure, from a woman's point of view, aiming for that top 20% is the thing to do.
Accept that, 80 women, (of each 100) are trying to marry 20 guys.
60 women are going to fail.
Unless of course, we start allowing multiple wives.
