That is the reason for debate and argument (to examine the defense). Opposing sides always see the opponents evidence as bogus. But that's where the argument has to be. If you are able to demonstrate the evidence wrong then the opinion really does not matter.And what if the defense is totally bogus, but you still believe you are defending it adequately? All those who hold to false beliefs assume that they are defending them, when in fact they are simply repeating the *mantras* taught by their religious groups.
