Dr. Craig is a liar.

[Jehanne]

All you have to do is provide me with: demonstrable, falsifiable evidence, reasoned argument, and valid and sound logic to support your claim that a god exists.

How does one go about falsifying the proposition that a justified belief must be falsifiable?

You can't, of course, but if a hypothesis cannot, in principle, be disproved, then it cannot be tested.  The evidence for "god" is no greater or less than IPUs or the FSM.
