I don't think (or rather, want to think) that people are being intentionally malicious. Instead, I think this is a scaling issue. Natural language being scaled in ways it isn't prepared to (e.g. over the internet to random strangers from all walks of life with very different intentions).

I've been looking for platforms where one can maybe more formally encode their thoughts, so that the argumentation and debating skill barrier is lowered / eliminated, along with manipulation. And I did find some, but they don't quite hit the spot, and even if they did, people aren't really on them, so it doesn't matter sadly.
