How, exactly, was it a private conversation? Do you not understand how social interaction works? And are you so flagrantly ignorant that you like to throw around the phrase "lynch mob" without knowing what it means, or do you really think that repeating part of a public conversation is similar to gathering a mob to murder someone?
Must be nice to lead such a sheltered life that you can so easily hallucinate about lynching.
"Prosecutor, judge, jury and executor [sic]...public summary execution." Um hello? NO ONE IS DEAD. Please stop for a moment and try to recognize just how ridiculous you sound.
