The Prop 8 ruling is bringing up old arguments about marriage and procreation. Even if one conceded that marriage was about procreation, which I don't, the notion that procreation is limited to heterosexual couples is ridiculous. Procreation is possible for lesbian and gay couples as much as for any couples dealing with issues of infertility. At least one person in a couple can contribute genetically if they are fertile. Fertilization techniques could even involve the gametes of both partners in the case of lesbians. For example, the DNA of one lesbian partner could replace the DNA of another in an egg then be fertilized and placed in the partner who donated the egg and lead to a full term pregnancy. Both lesbians in a couple could be related to the baby, one by genetics and the other by birth. Men can't give birth, but they can donate their sperm and be genetically related to offspring that they adopt. Homosexual couples can be as genetically related to their children as much or more than any heterosexual step family or adoption.
