You don't think Hillary had even more potential to do that given the left's much greater influence within the mainstream media -- not just news, but entertainment, etc.?
Honestly, I'm still seeing far more actual thuggery from the left than I am from Trump's supporters, and it's not even close.
Hillary is a footnote. Obama used all that to good effect to keep Baltimore and Fergusson going. He even sent out DOJ field reps.
If you want to discuss what HAS been done, you are certainly correct. The Left has the prize for rioting and mayhem. If you want to talk about what could be done, all bets are off.
Generally, folks on the Right don't riot in their neighborhoods, because their neighbors would take out the trash. Note, I haven't accused Trump supporters of rioting and burning towns.
Consider, though, that his campaign had two major bases, that of anger and of fear. Anger at what has or hasn't been done in the last 8, 12, 20, even 24 years, and fear of what Hillary might do. Those were effectively harnessed, and, on occasion, ginned up using half truths and falsehoods and directed at his opponents during the primary, too.
Those are powerful emotions and were harnessed to a great extent and effect using twitter, Facebook, and various fora on the web. The degree of anger seen was unprecedented in the last 40 years, and in the time I have been on the web, and the really disconcerting part was that it was not reserved for Democrats, but even those who supported different candidates during the primaries. Many who might have been persuaded to vote for Trump were convinced not to by his supporters' rancor as much as the man, himself.
To say that those same emotions could not be harnessed in the future by the same means, or that they could not be used to work up mobs like the Democrats and Liberals have, is simply disingenuous. That anger and frustration is still present, only looking for someone to blame.
