>>13577970>if you actually thought having a child with birth defects was wrong you would feel the same disgust towards anyone who had a relationship with a woman in their 40'sFunny enough while the chances double or more regarding certain conditions they remain relatively low in the overall scheme of things.
Incest will however fuck people up given enough time all day everyday.
>>13579985>still have a staggeringly high chance of having a child with down syndromeIncorrect, highly increased from the base chance yes absolutely it increases tenfold or more, but staggeringly high? We are still talking about like 1% chance.
Either way, compounded incest will produce one child with birth defects after another, there's no ifs or maybes about that. Which would be a clear argument against it.
