This means that even if preference for pink was purely by nurture (which I also consider unlikely), the data on toy preference strongly suggests that preference for certain jobs or activities is not purely nurture, and has at least some nature aspect.
Now, it is difficult to quantify how much exactly is the split between nature and nurture, one of the reasons being the fact that lots of what you would call nurture would never take place if a nature didn't provide people with preferences in the first place. However, blaming everything on "upbringing, culture and media" is certainly incongruent with reality.
>“War is a way of shattering to pieces, or pouring into the stratosphere, or sinking into the depths of the sea, materials which might otherwise be used to make the masses too comfortable, and hence, in the long run, too intelligent.”
― George Orwell, 1984
If people were really so equal, the NBA should be sued by Asians. There have been 2 (2!) women in history who have been able to dunk a basketball in a NCAA game. I could dunk a basketball in high school. Give me a break, the whole thing is ridiculously fraudulent. I would not want to work somewhere that had some bigoted, awful idea and attitude that a 'woman can not do a man's job,' I would never want to work somewhere like that -- but that's not the role of government to decide. We need people in government who are going to fight for civil liberties and human rights, people who will progress humanity off this planet and into the stars. People who will fight against corruption. Instead we get people who want to take advantage of people's feelings for their own profit or security.
