If you have a "disease" gene, don't you owe it to society not to propagate that gene?

No, because we're not in a position to decide who should propagate. We were not given a mandate to judge that by God. Eugenics is playing God. This leads straight to Brave New World lab-grown caste system society ran by a eugenicist technocratic elite.

God has commanded us to be fruitful and multiply. Why I'm not surprised this rabbi doesn't give a shit about the Torah and is in fact a naturalist and eugenicist instead? Almost as if it was the jews who pushed forward this godless "scientific theory".
