What Is In A Name?

Thou art thyself though, not a Montague.
What’s Montague? it is nor hand, nor foot,
Nor arm, nor face, nor any other part
Belonging to a man. O! be some other name:
What’s in a name? that which we call a rose
By any other name would smell as sweet;
So Romeo would, were he not Romeo call’d,
Retain that dear perfection which he owes
Without that title. Romeo, doff thy name;
And for that name, which is no part of thee,
Take all myself.                                  William Shakespeare - Romeo And Juliet.

For the non-literature readers, William Shakespeare was one helluva play-write, poet, actor and generally the greatest writer of all times. I love him and started reading his books when I was about 7 years of age.

In the excerpt above, we can see how the issue of "Name" was driving a wedge between the relationship of Juliet and her Romeo. "Name" here is generally about issues like family-background/kin/wealth-status/caste/etc. I don't understand why people feel the need to drive a wedge between a happily-loved up couple based on these emotional sentiments. You shouldn't stand as a barrier to the happiness of others simply because your selfish beliefs or opinion triumphs over commonsense. If a man or woman isn't physically or emotionally abusive towards his/her spouse, why pull them apart over things as mundane as tradition/religion/age-gap/wealth-gap/etc? I often wonder how Romeo and Juliet would have performed as a proper couple if they had been allowed to properly and positively follow through their strong feelings for each other.

Does it really matter what one's family's opinion on a couple's tradition/religion/age-gap/wealth-gap status is, for a union to flourish???
