I don't think the definition of "McCarthyism" is as narrow as you define it. I used that word because I though the analogy was appropriate and illustrated well what I was trying to express. Accepted definitions do not tie it to the use of government force, see e.g. "the practice of making unfair allegations or using unfair investigative techniques, especially in order to restrict dissent or political criticism." from
