So what you're saying, then, is that if objective reality doesn't exist, it's not possible to make rational decisions. Please, prove objective reality, exists.

So what you're saying, then, is that if objective reality doesn't exist, it's not possible to make rational decisions. Please, prove objective reality, exists. If you're not capable of making rational decisions, because the universe isn't objective, any proof you produce is irrational, but you may still claim to have proven objective reality exists, on account of the irrationality. It seems that we both agree that its not possible for people in non-objective realities to rationally decide objective reality exists!
