The problem that you share with brg444 is that you not only make claims which are unsubstantiated and too grand, you also encourage discounting of reasonable risks and concerns. This "answers" criticism without explaining it, which should not be your goal if you are looking for agreement with your position.
You do realise that most if not everyone of the concerns put forward by SC opponents in this thread can be qualified as "unsubstantiated and too grand"?
I'm sorry but all myself, and some others, in this thread have been doing is encourage discounting
unreasonable risks and concerns
