I'm assuming I'd have some kind of magical powers, then? First of all I'd have to start by thinking everything through a shit-ton and discussing with many people, etc. Just off the cuff, I'd probably remove the worst shit (wars, serious diseases, horrible crimes, large amounts of pain, etc, with some kind of preventative magical barrier), and then let people do what they want. Listen to if people have some ideas of what to do, maybe have some kind of council or democracy. As for inceldom, I'd try to argue people into agreeing with me on monogamy, using my magic to enhance my ability to make truthful and persuasive arguments. I do believe that if everyone was strictly monogamous (life-long), we'd only have a fraction of the incel problems we have now. Any remaining incels would have access to magical copes that could remove the desire for a relationship completely for a certain time (then they could just get another dose, but I don't want to flip peoples switches permanently or have them do so). I have nothing to say about skin color or politics, jfl.
