It's true that making judgments about someone without getting to know them is unfair. However, Nikhil is merely discussing a reality of infatuation—something that is a natural part of attraction in its early stages! After all, a fantasy is part of the experience of falling for someone. The retort also seems to overlook an important point in Nikhil's essay—that he is aware that the person he is attracted to “might be the worst,” and he is ready for the possibility of being disappointed by the reality. Rather than being shallow or unfair, this attitude actually requires considerable self-awareness, especially when it comes to recognizing that life rarely goes as planned.
Furthermore, Nikhil's essay emphasizes not only his readiness to accept the worst, but also his recognition of the beauty in such an experience. The dream of who someone could be can actually be seen as a way of appreciating their uniqueness. After all, if they did turn out to have all the qualities we desire, then they would lose their charm and become like everybody else.
That's why they call it an infatuation—the idea that someone could be not just beloved, but absolutely perfect. In this regard, Nikhil's essay is a typical description of a feeling that a lot of people can relate to; it's a genuine reflection of what it means to fall for someone. Let's not UrRong Nikhil on this one and simply enjoy his witty take on the wonderful emotion of love and longing.
