Motif: Opposing Forces Juliet knows that the only thing keeping her from her true love is the old feud between the Montagues and Capulets. The opposition of the Montagues and Capulets had even been mentioned to be an old feud that nobody understood in the prologue yet it is the reason for the biggest problem in the story. Shakespeare is poking fun at the barbaric nature of tribalism and how people separate themselves based off of trivial things like religion, race or social class.
O Romeo, Romeo, wherefore art thou Romeo? Deny thy father and refuse thy name, or if thou wilt not, be but sworn my love, and I'll no longer be a Capulet
Shall I hear more, or shall I speak at this?
'Tis but thy name that is my enemy. Thou art thyself, thou not a Montague.
