”If you look at the number of birth defects among individuals that are father and daughter or brother and sister it’s about 57 per cent and although you might go oh that’s absolutely terrible I would note that those individuals wouldn’t exist at all if it weren’t for the marriages that created them so they’re no worse off.

“Sure the birth defects are bad relative to not having them but it’s better to have those birth defects and exist than to not exist at all.”

…what the fuck kind of logic is that? You can apply that to someone living with birth defects, you cannot use that as an excuse to not prevent birth defects.
