Dalrock has found an interesting video about a woman, Kristen Jarvis, who has decided to manufacture dolls for boys. It's interesting because it shows the conflict within liberal moderns when it comes to the topic of our biological sex.
On the one hand, Kristen Jarvis is a very orthodox liberal. She complains that society says "be anything" but that people are still guided in some ways by being male or female. It is that basic liberal complaint that we cannot be wholly self-defining if our unchosen biological sex still matters. She believes that if boys were to play with dolls they would become more feminine and nurturing.
But liberal moderns live in the same world as the rest of us in which sex distinctions do matter: they are hardwired into human biology and are a part of our core identity and our heterosexual instincts. And so throughout the video you see glaring "unprincipled exceptions" in which these liberals don't follow the principle of erasing sex distinctions at all.
For instance, Kristen Jarvis had a very highly paid job as a lawyer, but admits in the video that she felt sadness and anxiety in not being with her children, and so she quit her job to be supported by her husband. Her maternal instincts won out. She didn't want to be away from her children and so she hired her sister to run the doll-making company. But this sister is one of the most feminine looking women you are likely to see - there is a mismatch between the purpose of her job (making manhood/womanhood not matter) and the effort she goes to in order to appear attractively feminine.
It's also interesting to observe the part where the sisters go to a preschool in order to test out the dolls on the boys. The best they manage is to get some of the boys to use the dolls for a rough sports game; one of the boys is pictured looking ill-at-ease with the doll; and one other looks glaringly offended at being offered the doll and rejects it altogether. The sisters admit that they have hurdles to overcome.
