In our put upon society with multiple levels of dysfunction, it’s hard to tell the difference between people who’ve been confused and disrupted who then become disruptive, or the people who are disrupting as their actual day job. I can’t tell you how to know anything for certain. But it’s all very well documented to be a real problem, so don’t let anyone tell you it’s not happening. It is happening. I’ve compiled ample documented evidence that should help shut down the gaslight on that score. (You can thank me later.)
The good news is that all you really need to know is that if something doesn’t make sense, it doesn’t make sense. I refuse to get caught up in emotional manipulation, superficial stuff, strawmanning, or hype, and I choose to focus on practical concerns.
