That matters a lot as to how we judge Givens' response. If she was confessing that her bishop had raped her, or her father beats her mother, or her family goes hungry to pay tithing....well, then, yes, Givens would deserve a smackdown for such a trivializing response.
I don't think any of us believe her questions were anything of that nature, and were probably more along the lines of troubling church history. In which case, maybe it deserves the smackdown and maybe it doesn't. It may even depend on that individual woman, since different things carry different weight for different people.
If, let's say, she was asking a series of common troubling questions along the lines of Joseph's polygamy/polyandry, the Kirtland bank scandal, the Book of Abraham papyri, and then threw in: "And why were church meetings all changed to Sunday and then reduced to two hours??" I think we'd probably all agree that a logical response would be: "Why does that matter?"
That's very likely exaggerating the insignificance of her question, but (in the interests of full disclosure) I sort of "pulled a Givens" with my own sister, whom I love dearly and who is probably the most loving, non-judgmental, Christ-like Mormon you could ever meet. She was thrown BADLY by the Gospel Topics essays. She would never read the CES Letter, and only read the essays because they were published by the church, but she was appalled by what they reveal about Joseph's behavior.
I didn't exactly say, "Why does this matter?" but I might as well have. She loves the church, she loves her ward community, she loves Relief Society, so DOES it matter---for her---what the church founder did 200 years ago? He's dead. He's been dead for centuries. It's a very different church than it was in Joseph's day, and Mormons don't worship Joseph anyway (or at least they aren't supposed to). So, does it matter, really? I was honestly asking and, for my sister, she realized it doesn't matter. It's not why she's a member and it has no effect on her faith.
The moral of the story is: When in doubt, ask your apostate sibling!
So that's what I'm overlaying onto Givens' anecdote, but, again: We don't know and neither does John Dehlin, yet he rips a Givens a new one, despite having no idea what the man was even responding to. It's possible Givens was merging a couple of anecdotes together of more than one person that he's spoken with. That would be an ethical way to maintain confidentiality and avoid the woman in question hearing that story and realizing that Givens is spreading her business around as a faith-promoting anecdote.
But we don't know. And neither does Dehlin.
With Bushman, I can see more of a reason to criticize him. And this may apply to Givens too, even though you have to squint a little to see it. But Bushman has straight-up said the orthodox narrative is false and unsustainable, yet he continues to claim that he believes it.
I can see a problem with that. It's dishonest and self-serving, especially when the success of their book sales relies on Deseret being willing to give them the imprimatur of carrying them in church-owned bookstores.
But, again, we know what Bushman said. It's on video, and it lacks any explanation as to how and why Bushman can say it's a false narrative, but then continue to claim he believes it. We don't have any idea what Givens was responding to. And neither does Dehlin, which makes the one-sided, Yelling At An Empty Chair and Pretending It's Givens episode really unfair.
