It shouldn't have to come to that. That should be well covered under the area of personal responsibility. My uncle (who was a successful lawyer) had type 1 betus and refused to have children because he didn't want to pass it on, he died of complications of type 1 (several decades ago, before insulin pumps and other advancements). I know a host of people with physical and mental impairments that are proven to have genetic factors and they still breed! On my first visit to fph years and years ago I posted a story of my classmate's sisters, who found her and her husband were both carriers of the cystic fibrosis gene (and fat) after having twin sons and one had it (a terrible disease for a kid to have with no cure and an early death), they continued to try to concieve again (obviously against doctors wishes). Fats are selfish. Fats are stupid. Fats are bad parents, because they're bad "people" (if you can even call them that).
