Who insults Romeo and Juliet's family?

Answer 1

I don't know whether we can answer this one, because it is not clear what family you are talking about. Since Romeo and Juliet are married, they both belonged to both the Capulets and Montagues. So who insults both? Mercutio, when he says "A plague on both your houses." The prince, too, says "See what a scourge is laid upon your hate that heaven finds means to kill your joys with love" which is admonishment to both families. The chorus, too, insults them when he says "civil blood makes civil hands unclean."
