Bullshit. Heroin is addictive no matter your biology or background. So are certain psychological triggers and mechanisms. Even the well adjusted get angry when they see various forms of abuse, for example. So if news is framed as abuse, victimization, etc it will trigger your oh so well adjusted self.
To illustrate my point I’ve deliberately inserted “bullshit” as my preface and “oh so well adjusted” as sarcasm. Be honest with yourself about how this anger inducing copy compels you to reply. You may not. But the feeling exists because you have similar triggers to the rest of us, and it is these that are being exploited.
Ps: Sorry about the sarcasm. Hopefully it makes the point.
