It never crossed my mind until it became a "thing." I know I do it but I don't try to exaggerate it. I'm certainly not going to try to hold an aspirin between my knees. (You young men may not know that reference.). I think some women just try to find something to clutch their pearls and get all butt hurt about these days. I will agree if a man is on public transit of any type they should be aware of their spread and do the right, polite thing and take up as little space as possible.
