First and foremost, I really hope it's not considered sexist that I have absolutely no idea who Kate Nash is. Never mind the 'Females Of All Description' pile, you could have slapped me upside the head with her record while singing her biggest hit and I still wouldn't have a damn clue what genre she truly belonged in.
Second of all, I hate to admit this - because I'm pretty tired of talking about literally every harmless decision having an -ist tacked onto the end - but this is kinda sexist. Female musicians, just as much as male musicians, deserve their own distinction and I don't think you would find too many people that would argue otherwise. That's why my biggest problem with this move isn't that it's disrespectful to a gender. I understand it's solely because I am neither a women or a musician, but my main gripe is that the employees at this hole-in-the-wall record store half-assed their laziness.
Honestly, what reasoning would a record store have for grouping all women together other than the fact that it takes less time than doing the research necessary to put them in their rightful spot? It's probably a nightmare trying to organize a new shipment. A duty I wouldn't wish upon my worst enemy. That's why the burnouts in charge should have maintained everyone's equal rights by doing the only thing a burnout should strive to do....less work. Throw all male records on one side of the room, all the female records on other side of the room, separate them with Boy George's entire discography, and everyone walks away happy. Well, everyone other than the customers that are trying to buy music in a timely fashion and the artists trying to sell it in an efficient manner, but what's more important - business or equality?
