"Dangerous misinformation" is a key phrase of many people on the wrong side of many different issues in the last few years. And it isn't as if we can't all recognize that there is misinformation in the world and some of it is dangerous. Yet, It is so commonly badly used by people using poor reasoning and poor argumentation to attempt to control others that just that phrase by itself has grown into a red flag. We really should, in many cases, dismiss all of it when anyone uses that phrase in their attempt to engage with us. Just dismiss everything they have to say. They are not open to reason, to rational and logical ways of good public discourse.
