Hi Judy,
a very brave decision to discuss such a controversial and almost taboo subject. You have done it sensitively even considering the feelings of those that might have been considered 'worthy' of termination. The practice of genetic counselling and screening of embryos can prevent the heart break of bringing another sick or disabled child into the world. Selection of fit embryos can be carried out prior to implantation rather than abortion of fetuses already naturally implanted. Using the same kind of techniques for designer children is not such an admirable prospect. Diversity is in itself a measure of fitness (for survival) of a population. It would be a shame to reduce that population fitness for the sake of fashion or desire for conformity to an imagined "ideal" phenotype.
You have not mentioned the problem of the abandonment or termination of many girl children in China as some parents have regarded a son only child as more desirable.That has now left an imbalance of the sexes in the population, which will I expect lead to future problems with not enough women to become wives of those sons. I have read that termination and abandonment of girls is also a problem in rural India, as there also boys are regarded as more desirable offspring.
An informative, thorough discussion of a difficult, sensitive topic. Good luck, Georgina
