I'm talking about asking for evidence when it's appropriate to do so, Ed. When the person HAS evidence, they will usually gladly provide it (proving their point). But all too often, you wind up getting abuse, and on the basis of that, you have sufficient reason to dismiss what the person is asserting if it does not otherwise make sense or you have reason to believe that it simply isn't true.

Asking for evidence to back up an assertion is not out of line in most instances.
