We'll get banned immediately on social media (facebook and twitter) if we were to organize an event like this. That is why we need Gab, Parler and Trump's social network to emerge as viable alternatives. And they must not use AWS (Amazon Web Services).
I have a gut feeling that Elon Musk will be teaming up with Trump as a VERY, VERY, silent and invisible partner Elon has most of the infrastructure in place already!! Elon is as fed up with the left as we are!!
