When you receive an argument from anyone, whether or not, you agree with or even respect the argument, you deal with the argument. YOU DO NOT ASK, WHETHER STRAIGHT OUT OR BY IMPLICATION, "WHO THE HELL ARE YOU TO SAY SO?" To do so is the height of incivility. It means implying that unless I am of a caste you recognize, you will not consider my views.

I said almost nothing of what you ascribe to me, anyway.
