Q picked the chans (started on 4chan) because of their proven ability to dig down into insanely obscure details with amazing speed once the autists there decided on a project, re: The jihadi training camp and the “he will not divide us flag”.
And the proven ability to generate memes that are very good at influencing a large and mostly ignored segment of our population.
This is one of the reason why the Q posts take the form they have. The point is to trigger the dig reflex in the annon autists of the chans.
That “he will not divide us flag” capture, not once but twice was amazing!
