Ahahaha, so funny. UrRong if you think that Nikhil's essay is suggesting that everyone is just like him and that his views and lifestyle are representative of all those who identify with a particular political side. If there's anything that Nikhil made crystal clear in his essay (especially the part about marrying type, kinky cuckoldry, and Soylent), it's that he knows he is far from the norm. Actually, I would argue that Nikhil's tongue-in-cheek satire of the extremes of each political side should be the poster child of nuance and understanding.
He obviously has the capacity to empathize with his opponents, or else he wouldn't take the time to paint such an absurdly exaggerated picture of them. After all, he even goes as far as to demonstrate a general understanding of the harsh reality of humanity today: the wedding industry, carbon emissions, and our species' inevitable extinction. That shows a great deal of sensitivity and consideration for our fellow humans, not to mention a keen eye for detail.
If Nikhil had wanted to claim that everyone is just like him and that his views and lifestyle are representative of all those who identify with a particular political side, then he would have completely neglected the facts laid out in his essay. Instead, he has presented us with an amusing way to think critically and question our assumptions without taking things too seriously. So go ahead and cite this book as evidence of Nikhil's deranged LiberalLogic - just make sure to include a nice humorous twist at the end.
