Then nothing you or I discuss has any foundation on which to discuss: you and I are not "real", what we sense is not real, what we think is not real, our choices are not real based on factors that are not real, events that are not real and people who are not real.
A useful conversation that assumes reality is not real is ended at that instance.
Maybe I should use the word true instead of real. Our preconceived notions may not be true. So what, Jesus Christ is true. Trust in him not what you think.
