Noting your inability to understand an/the analogy, and that the Mother/Father Talk is spot on, it comes down to this (what with taxation being robbery):
"Do you feel goods and/or services should be provided at the barrel of a gun?"
Pure and simple, taxation is force; it is theft. "Fairness" never enters into it. Your rebuke merely restates that taking from one to give to another is synonymous with a GPA point being taken from one to Help Balance Out another's GPA balance. Such is anti-American Democrat-thinking at its basest. A service provided at the barrel of a gun (as you unwittingly suggest), is not the answer.
