There are innate biological differences between men and women; morphology and to some degree cognition. The infinite diversity of human sexuality is also not at odds with biology, gender is not simply a deterministic XX or XY. In more extreme examples sexual dimorphisms within the same species such as the Praying Mantis show that differences can be pronounced. In things like cognitiion the differences must be quantifiable - the proper way to treat claims is scrutiny of methodology, other studies rather than reject them offhand. The same goes for variations between race and IQ.
Socially constructed biology echoes the concepts of phrenology and racial eugenics of the 20th century, the ham fisted imposition of political will with pseudoscientific terminology and justification. Claims had no objective testing, they were taken at face value, it was bad science and was rightly found out.
I accept the role of environment, including social, in the way that we develop, but there is an important role for biology in there. Society influences a lot of behabiour, the way that we talk, act, dress, interact, have sex etc. but it's still effecting what is effectively a biological computer with it's own innate potentials. For instance if by chance I didn't move when I was 5 I probably would have ended up a complete bogan, but I would still in principle have the same genetic potential. Such societal determinism will have an effect, just like biological determinism has an effect.
Biological determinism in action on me could well be shyness, as a blue eyed male who also happens to be very introverted bordering on the antisocial studies like this give pause for thought
In recent years, researchers have uncovered a link between iris pigmentation and inhibition/social wariness among young children (e.g., Rosenberg & Kagan, 1987, 1989; Rubin & Both, 1989). In the present study, 152 Caucasian preschool-aged (Mage = 54.09 months, SD = 5.84) children (77 males) with either blue (n = 84) or brown (n = 68) eyes, were compared in terms of parental and teacher ratings of social wariness, social play, and aggression. A significant Eye Color x Gender Interaction was found in terms of indices of social wariness; blue-eyed males were rated as more socially wary than brown-eyed males, while blue- and brown-eyed females did not differ in this regard. These results supported the notion that eye color is a marker variable for social wariness in young children.

There has even been a proposed mechanism for this statistically significant observation involving norepinephrine, keeping warm in cold climates and having a reactive nervous system and concequently a different temperament. Now that is a speculative hypothesis to be sure, but unraveling the cause of the observation can be done and could show a behavioural response due to a biological package, still the manifestation of biology can be different and may be fought. There is not going to be a gene for criminal behaviour or stupidity, an individual is the product of nature and nurture.
When the time comes I can have my genome sequenced for under a months pay I would definitely jump at the opportunity, I have a family history of heart disease and mental illness as well as longevity, lack of male baldness and intelligence - it would be an interesting excercise to see what could be genetic and what environmental.
