Suppose a person has an unstated belief.
They then make statement A, in order to lure you into unstated belief B.
You see where the conversation is headed and directly tackle unstated belief B.
Is it a strawman if the person believes in belief B to knock down belief B even though the person has not yet stated belief B?
People can choose to value so many petty things. Control is so important to some that they would resort to anything to get their results. Manipulating and conniving seem justified in their minds in pursuit of control. Little do they realize that most will see the manipulating and conniving in the process. How can that result in a favorable view of any belief? What are they teaching themselves and those around them? It's not good.
If one strives toward Truth, one doesn't have to worry about selling or doctoring the results. Further, If one is proven to be wrong, that just points in the direction of the real truth.
Isn't it time people stopped thinking beliefs are important or make one important? Won't Truth and Reality always end up with the best results?
Yes, there are many people as you describe. Point them in the right direction.
That's what I see. It's very clear!!
