It's internet culture. Where you used to have earnest twats in diners talking about this stuff earnestly, or the wingbats handing out their no spaced, handwritten mimeographed manifestos, they are now able to spill out their stupidest thoughts to millions at the click of a mouse.
I get it. It's the level of "earnestness" that constantly reaches new heights. I'm as game for an esoteric discussion as the next person, but expecting most people to even know most of these things ("you can change your emoji color") is ridiculous.
I don't remember where I saw it. Feel free to dig into whoever that is and compare with everything Anna knows about me.
