People who think it is their "right" to have a child or "right" to be pregnant no matter how "alternative" their living circumstances, should read Buffalo Girl's blog. Buffalo Girl is a woman who was conceived by an anonymous donor and is now dealing with the emotional ramifications of her conception.
Donor conceived people struggle with their identity, after years of being told that their donor parent merely donated a "cell"--end of story. It is far from the end of the story for these people who have had half of their heritage belittled for their entire lives.
Buffalo Girl also shows pictures of herself from the age of 2 to adulthood. She even mourns the loss of the ears she was born with, after her mother had them pinned back when she was 7. She has chosen to leave her own children's ears the way they are.
Children are a gift from God and should be loved and accepted as they are--not designed to fit our tastes and lives like window curtains to be thrown out when they no longer suit us.
