I also think it is sort of strange that Sandy and Daryl would promote or condone accepting nudity in their home so their children would be exposed to and I don't think it is appropriate to kiss your child's vagina to prove that you are raising them as gender-liberated. It is not about people being too focused on child sexual abuse or pornography... I don't think it's right to show children that is okay when if they were to do that to other children or grow up in a society where that is illegal but they don't know it-they could be arrested or violate someone else's person space.
I fully believe in civil disobedience and rebelling especially against this oppressive patriarchal society, but I don't think gender liberation has anything to do with telling children that nudity and kissing private body parts are okay, when in the real world, they could get in serious trouble for that. There is a point where you have to draw the line, and while you don't like society and its structure, you have to live in it, and you're not going to change everyone's thoughts right away so I don't think its appropriate to make children think that is appropriate when in society it isn't. At least you can teach your children that everyone else thinks that is wrong, and let them critically think about how they feel about that- children are often underestimated, but they do have the ability to think about things like that and make up their own mind. That would truly be liberation.
On a different note, I think that feminist books and cartoons which promote gender-liberation are good for children and while my sister thinks I'm nuts, my nephews really like these cartoons called "Free to Be Me..." and one episode is about William's Doll which Sandy mentions on page 106. I started showing my nephews this because my youngest nephew who is 4 years old like to play Barbies with our 4 year old girl cousin, but his older brother and the 4 year old girl cousin always teased him for playing with Barbies and I wanted to make sure they knew that it was okay for him to play with dolls if he wanted to so I showed them this cartoon. I posted it below. There are actually a lot of these good cartoons which promote equality between the sexes and even though they are from the 70s little kids still like them!
