Reality has a persistence and insistence and otherness that subjectivity does not.
And when we've defined reality, we have to decide:
1) Is reality an absolute, and therefore independent of any observer, or
2) Damn! There has to be an observer? Then reality is what an observer, each observer, says it is, and subjective.
But I, having absolute power, will decide whether reality is objective or subjective. Others will obey!
