A fair counterargument, but I think that the line delineating "psychiatric pathology" is not as clear as you imply. Many such pathologies are arguably socially constructed and sometimes even contagious in similar ways (see the book "Crazy Like Us"). I think "being vulnerable to social contagion to an extent that leads you to literally inflict harm on yourself" is definitely within the scope of being classified as a psychiatric pathology, even if it hasn't been yet. It seems like there's little difference between this and, say, anorexia.
