What's wrong with pink and blue?!

Don't get me wrong, when I have my baby they can play with whatever toys they want but I really don't see what's wrong with having a pink (or girly) or blue (or boyish) nursery and clothing for a whichever gender child I have. I guess I think people fuss about too much these days over gender and sex which seems to lead to so much confusion in children. It just bugs me. This post may not make sense to some people but I wanted a rant
