"It is not simply a case of 'preventing' the disabling condition. In PGD, early human embryos are examined under the microscope. Those who are affected by the disabling condition in question are immediately discarded (i.e. thrown away). One of those not affected is then chosen to be implanted in the mother's womb. The eugenic philosophy behind the procedure is very clear. Those who have a disability will always be thrown away.
"This has particular resonance for me, as I have several severe disabling conditions and use a wheelchair full time. I am painfully aware that such procedures disciminate fatally against those like me who would otherwise grow up with a disability. By discarding embryos with disabling conditions we are sending out a very strong negative message to all disabled people - that we are tolerated only because the technology wasn't available to eliminate us at the embryonic stage. It also sends out a very subtle message to those like baby Ethan, who were born after the PGD procedure - that they are loved and wanted only because they are not disabled."
While we know that Alison's letter has appeared in today's printed version of the Daily Mail, the text isn't presently on their website.
