I'm not writing to change anyone's behaviour. I'm writing to help people understand what's going on. It's none of my business what other people do unless their behaviour affects me.

I'm sure positivity works as a strategy if you're looking to start a mass movement or to persuade folks to do what you want them to. Demagoguery, fraud, infotainment, infantilization, or salesmanship would work too. That's a political or psychological matter, which differs greatly from the philosophical one.
