None of the above. What happened was that social media allowed women to get on the internet and do things they are interested in, which is mostly flapping their yaps and social warfare. Which is exactly what we see. Before social media, the internet was mostly men and the rules were simple and everyone was happy because women were not interested. After social media, women came online and started to talk in large herds and play female social warfare as they have done for probably a billion years. What we see now online is not stupidity but basically the noise that goes on between a womans ears - social media has hooked us up and we can now hear and see everything that goes on in a womans head. Which is basically little more than infinite detail about minutia and femal social warfare. There is a hidden sideffect to social media. Male social warfare deals with our placein the hierarchy and it usually involves violence. Female social warfare deals with keeping everyone the same, no one can have more or less than anyone else and their strategy is reputational destruction of their oponents. Social media cannot amplify physical social warfare, but boy does it ever amplify female social warfare. What you are mistaking as stupidity is basically just the noise in between womens ears + femal social warfare + sprinkling of feminized weak and pathetic men that participate in female social warfare because they are failed males that cannot get into a dominance hierarchy.
