An anti-debate appeal based on genetic fallacy, which attempts to detract from the validity of a statement by attacking the tone rather than the message.
In Bailey Poland's book, Harassment, Abuse, and Violence Online, she suggests that tone policing is frequently aimed at women and derails or silences opponents lower on the "privilege ladder".
In changing their tactics to criticizing how the women spoke instead of what the women said, the men created an environment in which the outcome of a dispute was not decided on the merits of an argument but on whether the men chose to engage with the arguments in good faith.

While anyone can engage in tone policing, it is frequently aimed at women as a way to prevent a woman from making a point in the discussion.
