Do you know what that makes me think of? It makes me remember so many Disney movies that I've watched in my childhood, such as Aladdin, Pocahontas, Tarzan, Beauty and the Beast, The Little Mermaid, Lady and the Tramp, Gnomeo and Juliet, and many more. In all of these movies, the main female character falls in love with a man who is not accepted by either their "people" or by their culture. Either way they are not meant to fall in love according to society.
Princess Jasmine, who is meant to marry a wealthy prince, falls in love with Aladdin, a poor boy begging, stealing, and pretty much just living on the streets. Pocahontas, the daughter of the chief, falls in love with one of the European men who invaded their land in order to dig and take the gold from it. Jane falls for an ape-man. Belle and the Beast, who can only be transformed back by finding true love, fall in love as Belle looks towards the inside rather than his appearance. Ariel, a mermaid, and a human end up falling in love. Lady, who lives with a high-class family, falls for, well, a tramp. Finally, Gnomeo and Juliet is an animated version of Shakespeare's play Romeo and Juliet, except for in the end they do not die. (It's a children's movie, they can't have the main characters die.)
Why would anyone go through so much trouble for something as silly as LOVE? Well, it's simple. Love seems silly to everyone except for those who experience it. When in love, people are willing to do anything, go against anyone, and even face some fears to be with that one person. It has been said that when in love, nothing else in the world matters to you other than that one significant person.
