It is not what a thing is called that matters, but what it is. The same applies to people
The quotation comes from Shakespeare’s tragedy, Romeo and Juliet. The two chief families in Verona, the Capulete and the Montagues, are long-standing enemies. Romoe who is a Montague, falls in love with Juliet, who is a Capulete, and she with him. Knowing that there can be no marriage between the two houses, Juliet laments that she was born a Capulete and he a Montague.
‘Tis but thy name that is my enemy …
What’s in a name? that which we call a rose
By any other name would smell as sweet.
