Legally, "pervert" is not a crime; however, the behaviors often associated with the label—harassment, stalking, and non-consensual acts—are. The danger of the phrase lies in its subjectivity. What one generation or culture considers "perverted," another might consider a valid expression of identity (as seen in the historical shift in how the LGBTQ+ community was once labeled).
The "pervert" wasn't a predator; he was a witness to a minor disaster she was about to have.
This linguistic shift forces accountability for actions, not existential disgust for identities.
However, in modern common parlance, the phrase has become almost exclusively sexualized. It is a label reserved for individuals whose desires, acts, or public behaviors fall so far outside the accepted Overton window of sexuality that they are deemed monstrous.
