I jest, but honestly, this article isn't that interesting. It seems to be a rehash of the entire individualizing 21c ethos of "be authentic! Be yourself!" (Just don't question why do all those authentic people all end up listening to punk music, drink IPAs, ride fixies and take photos on film cameras.) I find this view disturbingly narcissistic and, frankly, insulting to those of us who changed ourselves in the presence of others because we want to and like it. I would not be listening to country which I previously considered boring if I never dated a person who does. Am I a lesser person now because I have caved to social pressure or whatever?
It is also rather amusing that the examples of "polarizing" figures are a cookbook author and one of the less remembered figures or new atheism. Try telling others you like Richard Dawkins (whose polarizing views are precisely why he is still a prominent public figure.) Try telling others you enjoy Kid Rock (who I consider, at best, a boring musician propped up purely by ideological reasons.)
