Maybe it’s because I’m autistic, but speaking as a woman, I have NEVER understood this obsession most women have for height! As long as he’s tall enough to climb the stairs unassisted, and short enough not to get clobbered by the average ceiling fan, then what’s it matter?
Can somebody explain that to me logically?
It's because of evolution. Women look for the biggest, most protective mate.
nickcarraway got it right in his reply to your inquiry (reason = evolution), but let me expand upon it (because his brief explanation may have omitted certain intermediate logical steps, thus requiring the listener to make "leaps of logic"):
1. It is impossible to "reason" someone out of a "position" (political stance, preference, opinion, prejudice, etc.) that they didn't "reason" themselves into.
2. Women's initial preference for tall mates is a result of evolution - not conscious thought; women who mated with tall and strong men (who hung around) got additional protection and provisioning and were thus able to "out-procreate" their sillier sisters who mated with shorter and weaker men.
3. An additional, secondary factor is the so-called "Dazzling Sons" theory. Because of point 2 (above), there was a premium on taller, stronger men. Women who preferred such men on an instinctive level thus gradually out-bred women without such a preference. Gradually, women became consciously aware of this evolutionary preference and its real-world consequences - were able to verbalize it, communicate it, incorporate it into their lore, reinforce it socially, instruct their offspring to follow it, etc. Thus, a positive feedback loop arose. By this point, even if the evolutionary advantage conferred by height and strength became irrelevant (e.g., due to technological advances, labor-saving inventions, the rule of law, etc.), the social norm has already established itself and acquired such momentum as to constitute a "runaway effect."
All this plays into "Game Theory," which is perhaps why neuro-divergent people may have difficulty grasping it intuitively (I, myself, have come to acquire a basic understanding of it only after many years of reading).
Women don't generally have to "waste their time" brooding over such mechanisms of the Sexual Marketplace because - at least while still in their prime years - they are in a "Seller's Market" and hence develop an "Abundance Mindset." They are essentially getting "product" thrown in their faces, and so don't have to worry about understanding market mechanisms.
In their teens and early 20s, 80% of all men are, in contrast, in their "Lean Years," and only slowly entering their prime years. The have to "hustle" if they want to successfully market their "product." They thus have a "Scarcity Mindset," which favors spending hundreds of hours contemplating how they got there, what factors are responsible for their frustration, what they could do to improve their chances, etc.
