talking about the need for side-by-side memes… i am pretty sure the order has an psychological impact to the reader…
watching msm, the dude that got it "right" is always "right" hand side, while the trivial guy's opinion at the "left" hand side can always get "left" behind.
focus at some obvious msm fakenews… don't take my word for sure please. analyze obvious msm fakenews with that point of view in mind.
it will not hurt analyzing how they work, to improve the quality of a dedicated counter-measure…
