Disagreement with subjective/non-objective assertions is not negativity, it is positive.
Positive to you, negative to the person you are attacking. We are all subjects here, this there are no objective assertions anywhere. Not even yours.

A jargon phrase - what do you mean by it in this post?
It refers to the energy behind your posts. Or your choice to use that energy to criticize everyone.
