While it is slightly tempting to agree with this and say yes, they should be prevented from reproducing, such an action would have terrible repercussions. Aside from the fact that it is our natural right to reproduce and no one should be able to stop us, there would be so much more at stake.
First off, it'd be a massive blow to our personal freedoms. If the government had the sort of power to actually prevent someone from reproducing, what else could they do to restrict our lives?
Secondly, what would become of those who have inheritable conditions? Sterilised? Round up and shot? What about their dignity as a person? How would they feel to be told, "no, you can't ever have a child"? What about those with the recessive gene for such diseases? They'd have to be treated the same way so that such measures are eventually effective.
Thirdly, what would become of children who are born with these diseases after such a law or whatever is passed? Would they be murdered in the womb? Killed as soon as they pop out?
Anyone who would seriously support this sort of thing (like, outside of a hypothetical discussion on an internet forum) just may be better off in a totalitarian state :x
Really, there's no reason for anybody to have children.
Adoption, hello.
Even if you are actually serious, what about when all the children have been adopted? Heck, only allowing adoption would just turn those children into a sort of commodity - they'd probably eventually allow returns and trades since it'd the only way you can get kids. The selling of children would probably surface to the open as well.
also, Australia is awesome. Happy belated Australia day, mates!
