"Yes absolutely, have you seen the figures on Down's Syndrome births? I ask you bluntly are you supportive of the decline?"
I have not seen the figures on Down's Syndrome births, but if they are on the decline, I am supportive of this. Would you rather an increase?
"Forgive the blunt question, but you on record as being a qualified supporter of infanticide. Would that, for example, encompass, Down's births? Unexpected genders? Dark skins? Where do you draw the line? And would you draw the line in a different place before and after birth, if so why?"
It's up to the parents in consultation with doctors.
"Eugenics and abortion are not as easily partitioned as you suggest and this issue will become more acute as time progresses."
As of yet, you have not provided a definition of eugenics. My understanding of it is that it involves macro-level policies specifically aimed at some sort of genetic purity or specific genetic outcome. That is to say, the goal of eugenics is to make a stronger human race, and the means of achieving this involves an element of strong state coercion.
Abortion as I see it practised is the individual decision of individual women, and as such, has no broader societal aim. Even if you believe, as I think you do, that doctors coerce women into having an abortion, this does not mean that there is any macro-level policy aimed at purifying the human race. Even the justifications given in the article you linked do not approach eugenics; they are typically framed in terms of how difficult life will be for an individual family or for an individual.
"In passing In have mentioned gendercide several times now and you studiously avoid responding. If you want to leave that is fine, but I am interested to hear your views on the rights and wrongs of this large scale practice (hopefully without a wishy washy plea to education)."
The motivations of a particular abortion might be suspect, but I don't see this as a justification for prohibiting the practice entirely. Let us not throw the baby out with the bathwater (or placenta!). Ultimately, the decision is that of the mother, and it's not up to me to prevent it from happening. If you would like to stop women from aborting girls, then simply prohibit the tests for gender or prohibit doctors from revealing the results of the test. Of course, this should also be supplemented with education and/or a strong welfare state, but that's another matter entirely.
