Our responsibility in the courtroom is to seek truth beyond a reasonable doubt, but the article is not about criminal trials.

Our responsibility in society is to listen to people when they allege to have been harmed and to believe, at the very least, that something happened that left them feeling violated.  That's not the same thing as assuming what the other person did was criminal.  It's to accept that not all unethical behavior is criminalized, that some people are nasty, and that they too leave a trail of victims and are worth keeping an eye on, albeit informally.
