Some women go to short hair because as they age it’s easier for them to take care of. Or because a shorter cut gives more volume to thinning hair. Or because they want to switch up their style. Or because whatever reason they want. NONE of these things takes away from a woman’s femininity and it’s pretty sexist to suggest a woman with short hair is any less feminine than a woman with longer hair, or that anyone “gave” up any femininity just because of their hair.
I don’t see anyone in this thread talking about men giving up their manliness by shaving their heads. Or even suggesting that hair - on the scalp or on the face - is an indicator of manliness.
