The Sinclair parroting clip is not right wing. If it said "danger to our constitutional republic" then yes, that would be right wing. A democracy is what happens when a republic breaks down according to Plato's Republic. A democracy isn't a truly bad thing but what comes after it is. Worst of the worst. From there it returns to a republic and the cycle starts over.
This is either deranged or fundamentally dishonest. Where's the "debunked misinformation"? He responded to a post entirely neutrally, and people who seem to obsess over Twitter every day have taken it as a right wing statement.
