「嘘を嘘と見抜けない人に「なんでも質問」を使うのは難しい」

What's going on with the part in bold? What does that reduplication signify?

嘘を嘘と見抜けない人

Grammatically this clause has a similar structure to: "People (人) who are incapable (けない) of recognizing (見抜く) a lie (嘘を) as a lie (嘘と)."

In context, I think your sentence means "If you can't tell when someone's bullshitting you, you might as well not bother with the 'Any questions?' discussion board."

it's not reduplication. it's just grammar.

If you know　Use of を　And use of　と　it hsould be clear..
it's not hard... don't think too hard.
Like here'sa simpler sentence with that
嘘を嘘で隠す
Cover/hide lies with lies.

嘘を嘘と見抜けない人に「なんでも質問」を使うのは難しい」
the と is the quote thing "" not the "and" meaning と. Is that what's confusing you?

I agree with translation abaove, 　（The first translation。。。　I don't get the second one)....　So hard for me to think of a translation.

I rather liked that second one ('if you can't tell...'), personally.

It all makes perfect sense, expressed in dollars and cents/pounds shillings and pence.

Thanks everyone!
