Bertrand, I'm glad you started a thread to discuss termination as an intellectual argument.
Nipt means that in theory you can know the sex of a child very early on, Private tests will tell you, NHS might or might not, who knows. Nipt will in the future also be able to tell you other things about your child too, that people may think are good reasons to terminate for themselves. Personally, I feel if we're going down the designer baby route it is more ethically appropriate to sort the genetics out in a lab prior to implantation than terminate because the foetus is not living up to societies expectations of what a child should be, conditions incompatible with life excepted.
Women should be able to terminate until the baby is viable as a stand alone human, imho, which is roughly the current position here I believe.
However, I also feel there is a difference between terminating a child because you don't want it and terminating a child because you do want it but it was a girl/boy/ginger/ whatever and because it wasn't what you wanted/ the father wanted/ society wanted you now don't want it or can't have it. It makes me think of women in these situations like battery chickens or in puppy farms as something that can be made to have pregnancies over and over until they get it 'right'.
I don't know if the laws around termination will change due to advances in genetic testing. If current laws are to go by, perhaps women will have more opportunities to terminate to term because more disabilities will be identified.
It doesn't sound like the current law is that foolproof anyway, needing two doctors to sign off a termination because of the mother's physical or mental state does not sound like termination for any reason. In practice it might, but it would be easier to make getting to see two doctors that will sign it off impossible than it would be to change the laws regarding terminations in specific circumstances.
I think it is possible to discuss the impacts of genetic testing and the possible consequences of them without just assuming that anyone that wants to do so is not pro choice. I think women should be able to discuss their own experiences of genetic testing and choices around termination without censure or disbelief. I do not think that women should be denied terminations.
