There's a LOT of very low-brow, fast-food content on the "left", too. Videos that just makes fun of how stupid anti-vaxxers are, generate outrage about global warming while being very light on scientific data and hard of apocaliptic imaging, generate fear and anxiety about the rise of fascism and nazism, repeating the idea that Trump is literally Hitler and Theresa May is his Mussolini...

I'm not trying to make any point about whether those things are true or false, by the way. Just about the level of propaganda and emotional manipulation on both sides.
