One Direction fans are passionate about One Direction, or nearest equivalent

Oh, how much do One Direction fans love One Direction?

With a fierce and burning passion that can only be sparked by the band.

Or, erm, anyone who looks a bit like they might be in the band:

New Zealand teenage girls turned out in their thousands over the weekend hoping for a glimpse of British-Irish boy band One Direction but it seems not all knew who they were screaming for.

A radio producer wearing a beanie, dark glasses and a scarf, was mobbed when he left an Auckland hotel after interviewing the stars with young girls believing he was a member of the five-piece band.

Guy Parsons, 23, is older and taller than members of One Direction but still fooled the hysterical young girls who chased him down the street.

This could be a risk when you construct a band out of unthreatening bloke-types; it becomes impossible to recognise them out of context.

Interestingly, even when they had their error pointed out, some fans didn't care:

"I said 'I've got you, I'm not one of them', but they still wanted photos," Parsons told the Sunday Star-Times, adding he enjoyed his brief moment of fame.

There's a lot of critical theory which would tell you that boybands just fill a hole which gives young girls something to direct their passion at; this would seem to support that.

One Direction fans: incredibly passionate; just not that fussy.
