The ability of social media platforms to spread malicious propaganda intended to incite division is incredibly dangerous. The moment where a US president has refused to commit to a peaceful transfer of power should he lose the election is absolutely not the moment to test how well society can withstand the use of social media as a propaganda platform.
Society needs a long term solution for social media--my take is that it should be shut down completely--but this is a short-term emergency and now is not the time to let the perfect be the enemy of the good.
Being cautious is not a virtue when erring on the side of caution may lead to tanks in the streets.
