Dissent has to find a legitimate support, has to have some validation in the media, otherwise ppl might riot.

If mild dissenters or questioners or grumps are ‘represented’ by the Dems, by some TV shows, commentators, pundits, they can nod and say, right on, and feel they are still part of the total fabric of the US, their pov is out there in the public space, legitimate. This defangs them completely and keeps them quiet, buying charcoal for the BBQ, debating about supporting Hillary C or Obama - a *lot* to discuss over the beers and steaks.

Not to mention that any active dissenters are easily tagged if they join groups, so that disinformation campaigns and false-flag infiltrators can get them into trouble and separated from the larger group quite quickly. If someone starts a "Democrats for Death" group, then an undercover agent will join and offer the tools to get them into 'proper' trouble, when otherwise, they might have slowly educated people to stand up for themselves.
