Vallicella on define or drop, and the concept of faith

While Vallicella uses this as a critique of the left, I suspect it has a wider use. I suggest that in discussions between atheists and theists, once the word "faith" is spoken, the opponents ought to determine whether they can agree on the meaning of the term or not. In many cases I suggest they can't, in which case they ought to agree to use substitute phrases to express what mean on whose meaning the debaters can agree.
