Re: Pink crapfest
Not entirely - most of the pink preference is due to culture not biology. http://www.theguardian.com/science/2007/aug/25/genderissues
My grandfather preferred pink and red related clothing when he was alive and when we were in Thailand I saw more pink in the men than I did on the women.
If "women love pink and men blue" was completely biological then most or all cultures would have a distinct preference between the colours.
