Ok, having looked at the links, and walked down some stairs myself, here is my take so far:
1. The links did a LOUSY job of teaching/explaining/demonstrating the different gaits of men and women while descending stairs. It was all STILL SHOTS, even the "videos" were just slide shows. Very disappointed.
2. No mention is made of the PITCH of stairs (the steepness varies after all), good vs. bad knees, in a hurry vs. not, etc. CAN a man negotiate stairs in a female manner, for example? Does degree of "comfort" enter into it -- for example, trying to minimize danger of falling? What if someone is extra-cautious in this department? OR, is it one of those "physically impossible" things.
3. Why I need to see VIDEO instead of STILL SHOTS: when you're in the act of going from one stair to the next, your knees are NOT going to be side by side. It's like saying you don't open your mouth while you eat -- um yeah you do, when you put the next bite of food in!
I do know that men WALK differently than women, because of the different pelvis shapes. Also, men will sit differently. "Man-spreading" is the same as "sitting like a man". Just like "man-splaining" is just "being rational like a man".
I am also perfectly willing to believe that there are lots of trannies in Hollywood, considering the evil of that cabal, and the fact that the demon Baphomet is basically a mix of male-female. There's some esoteric, satanic admiration for transsɛҳuąƖism.
