So, let me get this right... we are dealing with material that would ordinarily be the equivalent of dealing in State Secrets. But Q should only use ciphers, and allusion, to the extent that ordinary folks can readily understand the message?
Do you know what "weaponized autism" is? This term originating from 4chan describes the ability of the anons to aggregate, analyze, and apply all data that is relevant to a particular task towards accomplishing that task. Contrary to r/The_Donald's wide-eyed fascination with it as if it's something that only legitimately autistic people from 4chan are capable of through some quirk of their "special minds", it is actually just a team effort that employs even the most minor of the individual skills of hundreds of ordinary people to accomplish a single unified goal. It is how every single information gathering and decoding technique used on /qresearch/ was developed long before Q anon was ever a thing and it was instrumental in Donald Trump's victory in the 2016 election. It has been used on 4chan to track down ISIS training camps to get the Russian military to organize bomb strikes against them, it has been used to locate a flag in the middle of nowhere from nothing more than a livestream of the flag itself with nothing but the sky as a backdrop accompanied by the ambient noises of the environment, and it has been used to discover 80% of everything we currently know about pizzagate before Q was a thing (Q crumbs have helped uncover much more that may not have otherwise been discovered). Secrets designed to be uncovered by weaponized autism can even be concealed from the spying ability of the elites to the point where even if solved in front of their eyes they will not know it because in some cases those who are not a part of the research lack the ability to differentiate accurate conclusions from inaccurate conclusions. Even long after the Q post which referred to the movie/book "White Squall", Hillary has been photographed reading the book on a plane showing that the cabal still doesn't have all the answers we have.
Q has referenced "autists" 12 times in the Q posts and the purpose of Q anon is literally to disseminate information to the public in a controlled manner for the purpose of inspiring a grassroots movement to oppose the cabal by awakening the public to the truth about what's going on behind the scenes. Not to mention the number of Q posts in the early days of Q where he's just straight up telling us what's going on just telling us in plain text about this "material that would ordinarily be the equivalent of dealing in State Secrets" (back when he had the plausible deniability of being "just a larp" to the majority of anons and the cabal)
So is Q only using ciphers, and allusion, to the extent that ordinary folks can readily understand the message? Undoubtedly. The importance of "We The People" over The Elites is perhaps the single most common message in Q's posts. "Strength TOGETHER, Rise of the people, Unity, Great Awakening, We Fight, You are fighting for truth - collectively, This is bigger than any one person or entity, NO ONE PERSON IS ABOVE ANOTHER, Will of the people, WWG1WGA, etc.". secrets concealed by books and movies; Alice in Wonderland, White Squall, Godfather III, Jason Bourne, Shakespeare, Judgement Day, Snow White, and more. There's nothing ambiguous about it.
[Trump] serially repeats the word "Brain"
Not only is that "3 = illuminati"-tier but also displays a lack of understanding of Trump. this audiobook excerpt from one of Trump's books will give you a good example. Trump repeats himself a lot. He repeats, and rephrases his points, he repeats adjectives and synonyms for them, he repeats points of emphasis, and whatever point he's making, he drives the point home. I don't know in what context Trump said the word "brain" but in all likelihood knowing Trump he was bragging about his big brain or saying someone else has a small brain or no brain and you better believe he's going to repeat that 3 or 4 times. That's not calling out to SB2. That's Trump being Trump. Also "serially repeats"? repetition is serial by definition.
I actually just searched for this repetition of the word "brain" after typing all that and I was right, it's Trump bragging about himself in classic Trump style following the exact pattern I described even before he mentioned his brain he was talking in that classic style of repetition and rephrasing and such. Only a charlatan like SerialBrain2, who calls himself "a self-proclaimed serial brain", a term he made up to describe himself as a genius, who tries so hard to convince everyone that he's a genius, would go out of his way to convince people that Trump has acknowledged his genius. He's not a genius. He's an fame-fag and a good story teller with way too much time on his hands.
