There's an obvious test of whether your claim that, if she's caught lying, she'll become a massive pariah: Ellen Pao, whose claims fell apart in a court of law thanks to evidence she was lying. Look at how the publications like the New York Times and people in this thread treated that case. Here's some quotes from the NYT article about her losing that is linked from this one:
"One of Silicon Valley’s most famous venture capital firms prevailed on Friday over a former partner in a closely watched suit claiming gender discrimination, but hardly got away unscathed."
'"This case sends a powerful signal to Silicon Valley in general and the venture capital industry in particular,” Ms. Rhode said. “Defendants who win in court sometimes lose in the world outside it."'
Neither the fact that her claims were found not to be true in a court of law nor the evidence contradicting them mattered as far as the press or public opinion were concerned. Just the fact that she made them in the first place was sufficient justification for condemning the company she accused and their entire industry.
