Anna Clark wrote an article that touches on adoptee rights. She discusses much of the misinterpretation of the adoption vs. abortion issue. This is the second kind of article that actually touches on the many issues inherent in adoption.
Adoption is truthfully not the answer to abortion. People use that against adoptees expecting us to be grateful. "Aren't you glad that you were not aborted?" This question is thrown at adoptees regularly. That does not increase the self esteem of an adoptee. Truth be known, the relinquishing mothers never really consider abortion as viable option for them.
As to why women have abortions, the economy is probably the primary reason. They can't afford to have any more children. With teens, it could be any reason why. However, that is where the schools and parents come into play. We as a country need to be teaching comprehensive sex education. Yes we need to teach our children exactly what their bodies do. We need to teach them how they function. We also need to begin teaching parenting classes in junior and high school. If our teens get pregnant, we need to teach them how to care for themselves and their children. We also need to teach sexual responsibility. If you have sex, you are responsible. This needs to be taught to both boys and girls.
