"Fortunately, the early commentaries on the Japanese achievement all suggest that attempts to create a human embryo from two eggs would be a crazy way for
humans to reproduce. It is tragic, though, that the main support for this assertion hinges on the health consequences for these manipulated embryos and/or a lack of availability of human eggs. While we certainly wish to protect the health of unborn children and are opposed to possible exploitation of women as egg donors, these reasons totally ignore the importance of holding sacred the sexual union between a man and woman. If Kaguya’s mode of creation were to be extrapolated to humans, the very basis of our society would be shattered—opening nearly endless possibilities for overcoming the normal reproductive barriers for mammals that requires both male and female genetic contributions."
What does Andrew Sullivan have to say about Kaguya? Gay marriage advocates cannot keep denying that this topic is important or keep hoping we won't know it exists. Kaguya exists. They must address it. Either they should demand the same right to create children together that male-female marriages have, or they should agree to relinquish the dream of having children with their partner, and with it, the demand for marriage and all the rights of marriage.
The middle ground of accepting the egg & sperm law but still insisting on same-sex marriage just won't work, because that would be a major change in marriage law. No marriages can be told they may not procreate. If we start saying some marriages do not have a right to procreate it would affect all marriages, all individuals. Procreation would be subject to a risk analysis. The only way to preserve our "basic civil right" to marry and procreate is to guarantee that all marriages have a right to procreate and everyone has a right to marry.
