I think the OP you responded to is being intentionally obtuse, you have made your point clear repeatedly. If you are aware you have CF gene and are also aware your partner does too, then you will not mate with them and instead find another mate. Some diseases can be eliminated like this.

I also have a condition similar to you and there is no way I'm letting another child suffer with that, so I'm not going to ever mate with a woman who carries that gene.
