I only wish you were right.
“Believe survivors” is a resounding battle cry in the war against rape culture. It is well intended, but like everything in this circus of social media the generally positive idea that assault survivors overcoming the pressure to keep quiet should be wholeheartedly believed and celebrated for their courage has indeed created an opening to ruin careers and/or lives.
An example that comes to mind is Eric Arndt, known in Pro Wrestling as Enzo Amore. Or at least he was until the truth of a sexual encounter was retroactively edited to make him out as a sexual assailant and he was subsequently drummed out of the industry, later to be exonerated and pointedly not re-hired.
Guy was/is seemingly a bit of a dickbag, but he is an example and you asked for one.
