I am aware of that and on your side, which is why I said I hate to mention it. Even in CF circles, people hotly debate things like whether or not it is moral for a couple to have more kids after having a child with CF, knowing they could have another child with a tortorous, incurable condition. I had my sons well before I had a diagnosis, so I never wrestled with that question. I understand why people would not want to knowingly inflict such a thing on a loved one. But it easily becomes a slippery slope of "people like you should not reproduce". However, I also feel strongly that you do not get good solutions by claiming genetics play no role, merely to try to avoid a political hot button. Life tends to be a bit more complicated than bigots or people with a political agenda want it to be.
Have a great day.
