I can only speak for myself. I have never suggested the posting of opinions that differ from my own constitute an infestation, or that they have prevented me from expressing my own views, or that people should be restricted in the number of posts they make, or that a "block" feature would be a good idea.  I try to the best of my ability to refrain from personal assessments and to present the facts that I believe support the positions I take.

I personally believe that approach is good for everyone.
