Suppose a worldwide genetic cleansing was happening. Every man would be an attractive Chad. Sure, there would be variations of Chad, but all men would be attractive and get tons of pussy nonetheless. All women would also be highly attractive and cute as well, variations occurring as well. Hell, some women would be futanaris. Traps would naturally be added too. It would be a hentai come true.

There would be no ugly or unattractive people. Everyone would have sex regularly and easily. To accomplish the eugenics, anyone deemed genetically inferior will be sterilized. Incels and ugly people will receive free surgeries to alter their appearances to become attractive, but they will not be allowed to reproduce. They will be able to have all the sex they want without worrying about ruining the gene pool or getting some bitch pregnant.

No genocide needed at all, just a mass sterilization and compensation. We would all become attractive even before we successfully cleaned the gene pool. If a rare genetic dud is made, then they will be compensated for so that they may live a normal life. They won't be allowed to reproduce, of course. Everyone wins in this scenario, even the incels. Think about it.
