CIVIL doesn't permit or not; we do. CIVIL is a platform that requires all of us to review each other as we post. That's why you review three other comments every time you post a comment. It is those reviews, which we all do, that determine to hold off some comments. If you see what does appear, we – you and I and all of us together –  don't screen each other for opinions or points of view. We – you and I and all of us – do screen out the useless name calling and insults and personal attacks that don't add anything to the discussion. Not because they are right or wrong, but just because they are a waste of time. They lower the value for all.
