You mean the failed persuasions were "crackpot talk" and the successful ones were "status quo". For example, a lot of persuasion was historically done via religion (seemingly not mentioned at all in the article!) with sects beginning as "crackpot talk" until they could stand on their own.
What I mean is that talking about mass persuation was (and to a certain degree, it still is) crackpot talk.
I'm not talking about the persuations themselves, it's the general public perception of someone or some group that raises awareness about it.
This also excludes ludic talk about it (people who just generally enjoy post-apocalyptic aesthetics but doesn't actually consider it to be a thing that can happen).
5 years ago, if you brought up serious talk about mass systemic persuation, you were either a lunatic or a philosopher, or both.
