When a non-expert brings a strong point of view to a complex discussion, the words might not mean what they seem to mean.
What might be being said is, “I’m worried. I’m afraid. I don’t understand. I am looking for solace.”
Answering emotional word salad with logical insight doesn’t do anything at all for these feelings.
If the argument you’re hearing isn’t based on what we know to be true, and doesn’t lead to a logical conclusion, it could be because it’s not actually seeking to be a productive discussion.
It’s awkward to say “yadda, yadda” but that might be what’s on offer.
When in doubt, look for the emotions and desires behind the words. People often don’t want their arguments to be heard as much as they’re hoping their emotions will be.
