Mazal, you really need to re-read my post. I did not say what you seem to think I said. In fact, my very first sentence says that I am NOT commenting on whether or not someone should have children or not, when there is a genetic disease. I specifically said they should consult with halachic and medical authorities, especially in a case where there is a clear propensity to such disorders.
I absolutely did NOT say ANYTHING WHATSOEVER about whether or not such a person should get married (where on earth did you get that from?). The whole purpose of Dor Yesharim is to help couples to get married in a genetically safer way so that they can have the best chance to produce healthy children BE”H. As to the miracle statement, are you telling me that what our Chachomim said about not relying on miracles, should be disregarded? I didn’t make that phrase up out of my head.
Please do not presume to know what health issues my family and I might have or not have. Everyone has his/her share of tzoros, even if they do not advertise them. Hashem should help all of us to have healthy children and grandchildren.
