|A small dose is enough to poison the conversation.|
But, No, HoweverMarshall pointed out all three terms as ways to turn any conversation into some sort of war. When I first read this, I remembered the good advice I received so long ago - and started to monitor these terms and how they are being used.
They are toxic because all three of these terms have the same meaning: "I know something you don't - I am better than you." The healthy exchange of ideas on face level becomes blocked as soon as one person starts elevating themselves above the other. What follows is often a toxic vindication of standpoints.
