It does involve the removal, and destruction, of developing babies who are often capable of life. Sometimes it's because of the personal ambitions of the mother. Yet we do things in society that are far more unnatural than cloning, and which raise huge ethical issues that few people debate. Artificial insemination by donor is one. Donated ova are another.
Adoption is a third.
A woman bearing a child that grew from a donated egg, is truly not giving birth to her own child at all. That egg-cell doesn't merely convey the chance of a pregnancy, but brings all its genes from the donor's family. The donated sperm confers inherent qualities that may be anathema to the recipient, when the child has grown up. Adopted children sometimes grow to have attitudes, or forms of behaviour, that are alien to their adoptive parents. Pretending that the biology of the donated eggs and sperm cells doesn't matter is blinding ourselves to reality, and in my view raises serious ethical issues.
