But I've already shown that it is not the key issue behind your wish to maintain a ban by comparing it with other unrelated couples who would have at least an equal chance of creating genetic problems in their offspring.
and I have already said that this is a separate issue that needs to be dealt with accordingly.
Furthermore, when it comes to a couple who for whatever reason are incapable of producing children that negates that objection entirely, yet you still want to maintain a ban.
yes, because otherwise it would be too hard to enforce the law.
I had a girlfriend once who was told by the doctors that she was infertile - she used to regularly have unprotected sex without the worry of pregnancy.
However, she miraculously became pregnant at the age of 30.
So the doctors were wrong here.
Thus, it is just a lot more straightforward to have a blanket ban here - the morality issue also backs this up.
Given the amount of posts that have been made now that's got to mean you either have no real objection other than your personal distaste, or whatever the objection is you think it’s acceptable to impose a blanket ban based on something you have no evidence for.
Like I have said , many times over - morality and depravity issues are a major concern here and thankfully, out in the real world, most people also agree with me on this.
