Let me state it more strongly: the definition of faith I gave is not only the historical standard from prior to 140 years ago, it's also the modern standard among religious scholars and in most religious traditions. It's only in the last 140 years, within one particular anti-intellectual religious tradition (and among critics whose primary experience is with that tradition), that "faith" means the other thing. Their usage is decidedly in the minority. As such, I think it's perfectly fair for people to use the more correct definition, and it's unreasonable for those who are ignorant of that definition to cry foul when presented with it.
