I appreciate the liberal sentiment. Indeed, we should be free to believe and to do what we want if we’re not harming anyone in the process. This is consistent with my hypothesis about the shibbolethian nature of beliefs. I’m just trying to explain how they work and how they differ from mundane beliefs.
But when you say that truth itself is relative, that’s more philosophically dubious. I’ve written on this if you’re interested. I take a pragmatic approach to truth that allows for the distinction between objectivity and subjectivity while leaving out the metaphysical glorifications of the former.
