In fact, *so* insightful, that I can springboard off of it to another level of truth.
Donald Trump is using the leftists' own social engineering tactics, in service of the truth, instead of falsehood!
What do I mean?
Look at the past political campaigns, BT (before Trump). Sam Donaldson or Brian Williams or Chris Matthews or someone would grab a line from a fringe-kook leftist site, and use it as part of a gotcha! against a conservative: Sarah Palin is an inexperienced Caribou Barbie, Christine O'Donnell is a witch, Ronald Reagan is going to start a nuclear war, George W. Bush is stupid; the GOP is racist homophobes; "war on women"; "macaca". That kind of thing.
The talking heads for the GOP-e, who mistakenly thought "well, people are basically good and honest, so if I just tell the truth, that'll set the record straight" -- only to fall into the maw of the press, who delighted in deliberately misquoting (as they tried to with Trump about a database for Muslims), or just lying openly through their foul teeth.
The net result, is that the ACCUSATION got discussed, and infinitely more airplay, than anything of substance; and when the air finally cleared, the news cycle turned over, the residue that left was the *association* of the charge with the GOP.
Trump is doing the same thing: exaggerating the truth, but in a "Social Justice Warrior baiting" fashion: they lose their collective heads like lemmings and scramble at all costs to virtue signal and call out Trump's heresy: only to find that they themselves are spreading the meme!
Good call, Mr. Trump.
Incidentally, you might want to seek out and read the book 'SJWs always lie" by Vox Day -- he used to be a columnist at TownHall.com or such. The book is available on Amazon.
More than half of the American public knows the media lies to us to promote their agenda (and that of the Left) so we are inclined to consider what they say is the opposite of the truth.
When Trump says, "there were muslim celebrations in New Jersey after 9/11," he is blowing the media dog whistle. The media immediately start barking that reports of such celebrations were proven to be false.
When the public hears the media scream this, they immediately reaffirm that the opposite is true and this points right back to Trump and underscores that he's not only speaking truth to power (power being the media) but also using the media to underscore the truth they in the media are so desperate to hide.
And by once again exposing the media, Trump is victorious. And his point made...we do indeed have a muslim problem (and the media is hiding it).
And there is one more benefit to the media dog whistle scheme.
When Jeb Bush and other candidates jump up to agree with the media that this muslim celebration story is false, Jeb et al align themselves with the lying media and tarnish themselves. Carson has figured this last point out which is why he jumps in to take Trump's position in all these situations.
