This is silly. I’m not in the practice of nor interested in rating what another person has to say, although I will sometmes argue with a commenter’s rhetorical tactic, hypocrisy or poor spelling. 

I bring what I bring. Although I appreciate civility, it’s not a requirement for me. And who get to decide what’s “civil”? Does that mean if someone thinks a commenter is a provocateur or simply makes a bad joke, a “peer review” will lead to the post being deleted?
Hey, how about that free exchange of ideas thing, huh?
