Good to read these elementary thoughts here. It's true what you're saying. Abbreviated statements that you've heard a dozen times are boring. Mostly when someone claims that taxes are theft, he says so on an emotional basis and suffers some form of deficiency. This often has nothing to do with taxes. More with the fact that the person who says this feels unfairly treated and misses emotional attention.

Did it happen to you that a fact-based conversation won't be very successful in such a case?

When you're talking to someone, whose job is it to interest you?

You want a witty conversationalist? Ask him witty and open-ended questions, which require a real interest on your part.

How have you experienced it when you still held on to a boring conversation or tried to convince someone?

Or did you experience, for example, that a boring conversation partner, after you asked him serious questions about his interests, could surprise you?

What if, on the other hand, you have met someone who, by asking you questions of interest, has given you a good feeling of inner coherence? What did this person do differently?

It seems you would like to maintain and build up this form of conversation, no? And I think that's good!
