The world needs to be purged of stupid - maybe some kind of vaccination
I'm not going to claim it is inhabited by the world's brightest sparks, but "stupid" is perhaps not as culpable for CA's output as it may seem on the surface.
I've looked at many of the Italian participants personal facebook pages. Aside from the Charlie oriented content, they look eerily similar to a fair few of my facebook "friends".
The "friends", who I know in real life, are less hampered by stupid than they are by a certain amount of social isolation and a lack of opportunity for shared emotional expression. While nobody I know on my side of the Alps has jumped into this specific case, they do have form for joining in other newsworthy stories and issues.
IMO the main attraction is the opportunity to have and express strong emotions (feeling like their life is not just a long trudge of mundane, small struggles) and the chance to bond with other people via those shared emotions. When they do that it seems to me that they tend to display their true intelligence/education level as lower than it actually is. Maybe a kind of intellectual "choked by emotion" thing going on? I have also noticed what could be a (possibly sub conscious) act of "dumbing self down", perhaps to avoid alienating the less articulate bondees. And maybe also to create "salt of the earth" strong contrast with "the enemy". Which tends to be authority figures, meaning quite well educated, facts over feelings orientated and typically reasonably articulate.
Again, not suggesting CA is an Einstein-esque union by any measure. But what they are capable of intellectually right now may be dampened and rendered less visible because of "dander up to the power of eleventy" issues. And possibly a symptom of some kind of group dynamic ?
People like this have always existed. Always. What has changed is that the barrier of geography has been swept away by social media and they can now group together in numbers that were previously not possible, well not at this sort of speed anyway. And I have no idea what the longer term outcomes of that are going to be. But don't feel wildly optimistic about them.
