I’ll add to the votes that we’re a lot more likely to be destroyed by neglect/cost-cutting by the powers that be than any sort of directed takedown, though it’s certainly a non-zero chance. The reason though for the second to be slightly more likely than the norm isn’t (IMHO) because of our screeds against Trump, but because we have a number of obsessive love-hate Trocks that might make it a point to try to whip up (negative) interest in us. And even then, I consider it a low order priority.
For that matter , it’s been mentioned in many other threads that in the event of us losing the SDMB, some of our members are able to create a (hopefully equally moderated) Reddit, or other forum, though given the example of losses due to the migration to Discourse, it might be a fatal blow anyway over the medium term.
And there are of course other options in terms that many of us are thinking loudly be being too polite to explicitly mention out of deference to board rules.
Back to the motivation and political futures of social media and message boards… while I’m not sanguine about the future at all, my hopes revolve around two facts so far. One, the Republican fervor for Trump seems largely focused on him and him alone. Sure, there are plenty of smarter, and just as evil bastards out there that would do more deliberate damage, but none of them seem to have the universal appeal he does. And, following on to that, Trump is old, and his mentality and actual health are very open to doubt. If we’re luckier than we’ve been to date, he could drop dead or into a vegetative state soon (to your noodlely sensors oh FSM) and the infighting over who would wear the mantle could give us a chance to claw back from the edge.
Honestly, I don’t think we’ll manage. As said in many other threads, the magic of democracy is that a critical mass of citizens believe in and want it, and it sure looks like the critical mass is in the other direction. Whatever grows out of the infighting I mentioned above isn’t going to unlearn the fact that far too many people want a popular dictator and our traditions are zero effective protection to someone who doesn’t care.
And that’s leaving out (and back to the OP) that another factor to make Democracy work is at least a basic agreement on a shared reality. And social media bubbles in general, along with a bloody-minded willingness to ignore it in favor of “secret knowledge” and general lack of curiosity, may have killed that factor as well.
