If science can prevent the disabled from being born disabled eg through germ line therapy, then parents must be made to have that treatment prior to conceiving.
We stand at the brink of a new society - one where no more disabled children with inherited genetic defects need be born anymore to suffer as a result of those conditions.
We now have technologies that can ensure parents do not have to bear the burden of caring for disabled children born with genetic defects and that disabled people are not born to suffer due to those defects.
The time has come for society to change to adapt to new technologies - and this includes compulsory pre-pregnancy screening.
Those that refuse lose all rights to benefits.
If they want to have a disabled child, then they have to pay for it, not the state if they have refused screening or got pregnant without screening.
If they get pregnant without screening - they pay for the child, not the state.
The states role is to provide resources to hospitals to allow all women and men to be tested prior to having children for genetic diseases and if a problem is detected to provide them via gene line therapy and IVF the chance to have a healthy child via the NHS.
Why should society pay for their apathy, ignorance and selfishness if they just decide to get pregnant and bring a disabled child into the world.
