If you really believe this then this isn't the website for you. This is from the Forum Guidelines:

4. Points should be supported with evidence and reasoned argumentation. Address rebuttals through the introduction of additional evidence or by enlarging upon the argument. Do not repeat previous points without further elaboration. Avoid bare assertions.

But a discussion about how one supports positions if not with evidence would be fascinating, and if you propose such a thread over at Proposed New Topics then in my moderator role I'll give it a look as soon as I can.--PercyEdited by Percy, : Fix typo.
