Not this old chestnut again. It's been proven that even when you remove everything that might influence a child towards a gender specific toy, boys still favour cars and guns, and girls still favour dolls. I've even spoken to feminist friends who were adamant they had shielded their children from gender stereotypes, yet saw the same results. What is so dangerous about the idea that male and female may want different things as a consequence of biology? Shouldn't our differences be celebrated rather than be suppressed?
