Zwicky your right that hetrosexuals don't have a monopoly on the ability to provide love, care and a stable, nurturing environment for children. But they DO have a monopoly on being the natural parents of their children. And although feminists and lesbians continually say that biological connections between child and parent are of no value, the evidence would indicate that it is of value to both parents and child. That being the case why would an adult who claims to love a child deliberately manipulate the family structure to deliberately deny that child a proper relationship with both its natural parents. The answer of course is found in the feminist mantra - "It's all about me, it's all about me, it's all about me".
