I can absolutely compare that to online conversations as they have lead to at least one attempt to overthrow the US government and have convinced an alarming minority of armed citizens that lizard people are real and pose a threat to the children of the world. That propaganda has always existed is not in question, what you fail to address in your response is the caustic effects on society caused by the proliferation of information sources.
I apologize, but if you think those things are comparable there is no way we can have any kind of fruitful conversation. Our values and perspectives are too different.
