Yes tethersend it is true that "girly = crap" is not a great feeling to have either.
It's so complicated. As a not very girly person, and one who was good at maths and liked "boys" things and so on, obviously I find it hard to understand how it could be that females would genuinely prefer things that are "girly" and really not want to get involved in "boys" things.
However it is a big wide world and having read many threads on here I understand that honestly some women do feel very different to me, and obviously I have to accept that is a genuine feeling. So we're all different, so far so good.
It's the difficulty that in our society things that are "feminine" are indentified as inferior and flimsy and silly and not worth much - from all sorts of interests to work. Thus there is a problem that doing the feminine thing, if that is what it is in your nature to do, automatically results in lower status things that are laughed at and considered unimportant. Then on top of that the additional problem that both sexes are steered into the stereotypical roles from the moment they are born (and before, sometimes).
In an ideal world we could all be whatever we wanted, and there would be no difference in vaules attached. A woman with a penchant for shoes would not attract more assumptions of frivolity than a man who liked expensive watches. Everyone could get on with it.
But at the moment while "female" things are lower status, and girls have stereotypical bevaviour reinforced so forcefully, it is best to be on the alert for it getting too much, becoming all that they are.
