This doesn’t eliminate the “problem.” Women are still conceiving babies with Down’s Syndrome. To put an end to the problem, I propose that Icelanders all get sterilized. There will be no more babies with Down’s Syndrome.
Of course the m*slims will not get sterilized, and will replace all the Icelanders in 114 years. But that’s happening now anyway, just slower.
Absolutely fool-proof way to get rid of every human problem.
