You are far too critical of other people's comments.

I suggest spending more energy and focus perfecting and improving your own comments rather than wasting your own time criticizing comments. Also, if other comments were so poor, why would they even warrant a response? A down vote and move on.

If you, in principle or concept, disagree with someone's comment or theory, then take adequate time to address specific points you disagree with and offer up your own alternative theory as proper rebuttal.
