I don't describe my beliefs as eugenics, and I think it's unfair that you do, but I don't get to decide what you label me. There will never be a government agency that tells people they can't have kids. I would never advocate for such a thing and it's frankly impossible in practice even in the most totalitarian of states. What I would like is for people to make honest appraisals of their means and ability to be a responsible parent, which includes the genetic component. I will frankly state that I think less of people who knowingly bring sick kids into the world. Medicine does not exist to try and ameliorate the consequences of peoples poor decision making. Fate throws us enough curveballs, enough suffering without having to deal with conscious stupidity.
