if things and activities were not "gendered", why bother using them as gender defining attributes.
there is a social feedback loop i guess.
are you female because you like pink stuff or do you like pink stuff because you are female. and what about females that do not like pink very much.
and is pink stuff for females, because they like it, or do they like it because it is for them.
i wish there were an internal gender sense. but there is none and not even brain scans can distinguish between male and female brains. so hopping on that giant social feedback loop is what we have. gender does not exist if you are alone in a vacuum.
