Apognophos (4) "We should respect the fact that other people will not accept what we consider to be facts no matter how hard we try."
This is also true. Respecting other peoples right to illusion is a noble thing. I deliberately allow certain illusions to exist in my life because it is in my interest to do so. However I know they are illusions and do not seek to convince others that they are facts. I would do that only if thought sharing would help others and if I could prove my assertions. Otherwise I keep my illusions to myself.
I have some sympathy with your explanation of individuals right to interpret life according to their own needs and wishes. I can see that you are keen to keep things friendly on the forum and probably in real life. (It tend to be that way myself, though I do have a cut off point if pushed too far)
What I have tried to offer is the value of separating fact from fiction. There is some benefit to our subjective inner world, and to personal interpretation of facts, though out there in our fast moving and dangerous world, objective facts are an essential survival tool and need to be kept in a separate tool box.
