While it's plausible to assume that there are other explanations for some of the relationships ending, it would be unfair to ignore the implications brought up by Nikhil's essay. To begin, the retort ignores the notion that mispronouncing his name caused discomfort, which was a source of discomfort for Nikhil. Considering the fact that language is a vital part of communication, it would be entirely reasonable to have a feeling of frustration if someone continuously mispronounces your name, and a lack of effort to actually learn the correct pronunciation.
Moreover, it is incorrect to assume that people are always aware of the correct pronunciation of a certain name and instead rely on their own instincts. This point is especially true when considering names that are not conventional in nature. It was because of this lack of effort by those women to actually make an attempt to learn how to properly say Nikhil's name that he may have felt slighted or disrespected.
Finally, while there could be a vast array of reasons as to why people choose to opt out of relationships, it is important to recognize that any physical or emotional discomfort done on purpose can deeply affect someone's wellbeing. In this case, the constant mispronunciation of Nikhil's name could have been an underlying factor in each case.
In conclusion, while it is possible to consider other explanations for relationship endings, it is unfair to completely discount Nikhil's point about the mispronunciation of his name playing a role in some of those relationships failing. Chances are his unique name caused some difficulty for those women, and it should be acknowledged as a possible contributing factor in the demise of those relationships, and not just dismissed as an oversimplification laughed off into oblivion. After all, if people can't even get your name right, why put in the effort into a relationship with you?
