That's all very nice, Zlex.
However, if you can't see the difference between an act which will kill or harm independent, viable people, and an act which kills dependent, non-viable foetuses, we have no point of contact at which to have a discussion. Whining about DNA isn't going to make any difference, because human suffering, and not existence/non-existence, is my concern. To knowingly cause human suffering, whether now or in the future, is not okay. Stopping a line of potential descendants from coming to fruition before it has even started is a completely different act with completely different moral consequences.
I find the sort of selective abortion you refer to (OMIGOD HITLER DID IT; I call Godwin) a troubling notion only because of the implications for the character of the sort of people who'd think that was a good idea. You'll notice that we already have selective abortion; foetuses are screened for disability and deformity and many parents, rightly or wrongly, decide to abort. However, the reason for an abortion makes no difference to the foetus. The foetus is dead, either way.
I can see you dragging up counter-examples ("What if we did something now that caused all the pregnancies of some generation in the future to spontaneously abort?"), but these all need to be measured in terms of human suffering, and by "human" I mean post-birth individuals. DNA is a red herring.
There is no OneSizeFitsAll response to anything, including murder in the feral wild. There are lots of human traits that are 'taught' out of feral mankind.
Indeed, I've never met anybody who has actually had an abortion that felt wonderful about it.
My wondering about this is not a hostile act; I don't believe, for instance, that the gov't should make abortion illegal, but neither do I believe that anybody should be campaigning to make it a Holy thing, a 'right', a proud moment in the history of mankind to be thumped like a ribbon on the chest.
I'm saying this as someone who is deeply ashamed that I only accidentally did not 'terminate' the
process that is my youngest son, who is definitely not a pimple.
I wonder, if only for myself, where my own once rationalization
came from. We'll get a CVS test, they'll test for a handful of known defects, if any pop up, ZIPPPPP! no problem, flush the inconvenience/cost down the drain, and back to the Banquet Table.
Why else do you ask for a CVS test?
That was me and my wife, perfectly willing to rationalize our Holy choice, and permitted to by the cloak of a temporal bias(ie, he, incomplete with his genetic deletion/Williams Syndrome which snuck by the CVS screening, just wasn't here, yet.)
It would have been easy, because we didn't know him yet. And, we could have fooled ourselves into believing that the impediment to our actually knowing his process was other than our active decision to terminate it, which would have been, in fact,
the only impediment to that which now makes it impossible to comprehend without feeling sick to our stomachs.
I've been accused of 'torturous logic,' because I point out the logical truth that every single factual instance of hypothetrical future generations arrives 'here' by way of the state of being merely conceived. I'll accept it as 'torturous' when someone provides the first counter example.
At best, I am told that the Royal 'we' should only have ethical/moral concerns for the nameless purely hypothetical future generations, but
none whatsoever for the far less hypothetical actual instances of them that actually show up knocking on the door as explicitely invited processes more or less on their way to an inevitability.
There is
something that gives us all pause, or at least,
should give us all pause, when we consider taking a dump on merely hypothetical future generations,
none of which that we actually know or love yet.
What is it, and where does it go when considering the merely conceived, and why? As best as I can see, the 'why' is, because the costs and inconveniences are immediate, and because we can.
In other words, the same old selfish instincts that the better angels among us claim to scoff at when they condemn some bastard burying toxic waste in some short term disposal scheme because it was 'more convenient and less costly' then considering merely hypothetical future generations that we don't know or love yet.
When he says to us,
today, and not 50 years ahead in some continuum of time when we will know and love folks unborn today, "But it will last 200 years," on what basis do we say 'ick' that is not good enough?
