Worse, Wampole mistakes some honest pursuits for fads. Why should we dismiss an interest in vinyl, or in SLR film cameras, as ironic faddishness in the first place? You can argue for vinyl or film on their merits--better sound quality, for example, or the tactile pleasures of working with knobs, dials, and levers versus Graphical User Interfaces.
Finally, who's to say that something lived ironically can't ultimately be appreciated for its unironic charms? (Why assume, IOW, that 'outmoded fashions' are destined to remain outmoded?) I say this as someone who's contemplating revisiting the handlebar moustache for a third time--I've just come to like the way I look as a Frito Bandito.
Observe a 4-year-old child going through her daily life. You will not find the slightest bit of irony in her behavior. She has not, so to speak, taken on the veil of irony. She likes what she likes and declares it without dissimulation. She is not particularly conscious of the scrutiny of others. She does not hide behind indirect language.
Ironically enough, one of Wampole's prescriptions to a 'self-infantilizing' generation is to take on the earnestness of a child. But that's already been done, Christy, by Zeitgeist poster children Animal Collective. Fucking hipsters.
