She got a man fired over a private conversation. One of the rules of civilized behavior is that you don't do that. Briefly ignoring both that she did not "get [him] fired" and that your definition of "private conversation" apparently extends to "conversation in a public place that others can easily hear", there are plenty of obvious situations in which a private conversation can and should result in consequences (sexual harassment and threats being clear examples). Your position on the rules of civilized behavior is incoherent.
