It is true that children should be protected from profanity until they are old enough to understand the implications of using such language. However, Nikhil's original essay has some truth to it and it cannot be so easily dismissed.
As Nikhil rightly pointed out, teaching children that profanity is a tool used by grown-ups can help them to differentiate between when it is and isn't appropriate to use certain words. With the right context and understanding, rather than simply censoring them, children may be able to learn why using certain words in certain settings can be good or bad.
Furthermore, Nikhil's essay suggests that children should be encouraged to use profanity as a tool of expression. This is beneficial because it allows children to express their emotions more freely and can even help with their emotional regulation skills.
Finally, Nikhil's essay highlights the fact that teaching children about the nuances of profanity can help them to develop healthy language habits and respect for authority figures. Instead of simply censoring profanity, if children are taught why it is inappropriate in certain settings then they will be more likely to understand why it can be damaging if misused.
In conclusion, while it is important to protect children from profanity until they are old enough to understand its implications, Nikhil's original essay has some merit and should not be discounted lightly. After all, what better way to ensure that our children grow into responsible adults than teaching them how to properly use an otherwise powerful tool of expression? UrRong! But you have to admit, "Then fucking feed me, you imbecilic whore!" is funny.
