If a person wants to think everything is fantasy and fiction that is their choice, the very definition and meaning of reality is shared by many, therefore it is not merely just perception of the individual. I have showed that there is universal truth and a shared reality, you just haven't found the information compelling and do not understand/believe it. Trying to render an argument false on the grounds of personal exclusion is contradictory. Everything typed could be considered ones own perception, but that is not the point of debate. That is to present arguments based on logic and reasoning. This is done through explanation using words like reality which have shared meaning, that shared meaning is defined above. Check the Philosophical definition #5 and contemplate the paradox of even speaking of reality, is reality congruent?
