addendum: with respect to 1a I haven't seen it suggested that the protestors are being paid. I've seen it suggested that a few key organizers are being bribed and the rest are mindless followers. For instance the insinuation that Nathan Law got into Yale as "payment" for "helping to split China". How could I ever disprove that the CIA arranged someone to be admitted to Yale? Its an unfalsifible yet plausible claim. That's what makes trying to disarm it fun!
