Maybe this kind of division was massively adopted because it allows to easily categorize groups of people for different purpouses, positive or negative. Makes for easy labelling and blaming without critical thinking or analysis. I hope this generation meme dies off, but I think it will take a while, it’s very convenient, mainly to advance certain agendas.
I think reddit model should be as a non profit org., something like wikipedia. No ads, no selling or trying to monetize user data, or being hostage to its investors whims. That would require a complete change of management. Only then I would think about going back.
