Men were men in those days, they were courteous and there were no soy boys and skinny jeans wearing wusses.
I think it has more to do with too many unnatural pressures on the female sex at all ages and levels of development, they never get a chance to feel nature and allow its influence on their paths.
They are not doing the things that make them happy and fulfilled.
Men are better at shutting out the noise and living for themselves so the effect is less on them but each generation of males is facing more and more what the females are facing, an unnatural life and forced roles that doesn’t fit their nature, the boys are showing terrible cracks as well, but we never depended on them to be the center of home and family, the males can be brought into a domestic family life if the female sex is calling to them, but that calling is being cauterized by institutional, business, and political forces exploiting the female.
