So here's another point which attempts to step out of the quicksand. Objectivity depends upon specifics which can be pinned down and analyzed further. Subjectivity consists of vagaries which cannot be identified. Here's another point. Objectivity includes rationality, where one point is related to another point to develop consistent relationships.
Subjectivity allows no relationships between points.
Each point is a stand-alone claim, which rests upon the supposed knowledge of the person who makes it, and no test is possible to determine whether it is true or not. Objectivity requires making only those points for which there is evidence to substantiate them. If there is no evidence, a point should not be made. Subjectivizers never follow that rule. They subconsciously do the opposite in their attempts to evade accountability.
