Applies to everything, not just sexes. The prejudice needs to stop in all forms.
To your point, as a kid, I remember that scene from The Sandlot where the ultimate insult was "You play ball like a girl!" and I had that thought like...god damn that's fuckin cruel. Like, I'm sure that shit pissed Jenny Finch the fuck off. That girl can throw some Olympic softball heat that'll shut people down. Pretty sure her husband proposed to her on her college pitching mound because she was queen of that mound.
My sister's a better basketball player than me and I have her by several inches in height.
