How do you define reality? I asked you. It wasn't a rhetorical question.
Something can be true, and also be subjective. In my view truth (and reality as we know it) is the confluence of overlapping perceptions.
It seems like you define reality as "objectivity" or "materiality" but both of those ideas are only concepts and words that we have in our minds. What we think of as materiality comes from our perception of reality as observed through our senses (subjectivity).
I'm not saying there is no reality and there is no truth, but I'm saying "truth" as you think about it, is not something that exists separate from your perception. Because even the concept itself is part of your perception, part of your consciousness. Do you see what I'm saying? This isn't saying it's false, it's saying it's inherently subjective because there is nothing that you can know that is outside your own consciousness.
