Except, there have been several attempts to start Asian magazines entitled "Banana". I'm not sure if any of them are still in print, but why would they be called Banana if they were considered derogatory in the Vancouver and NYC community?
It may seem dismissive and patronizing to you but apparently not to them.

"The choice for the name Banana is meant to be an inside joke. For anyone who has ever been called a ‘banana,’ you know that it’s a nickname that has been given to many first generation Asians growing up in western world, like us. It’s not meant to be derogatory, but celebratory. "
"The term can be borderline offensive; it implies a limited view of classes of people, and more unfortunately, may impose negative pressure on an individual’s self identity.
Knowing precisely this, friends and creative duo Kathleen Tso and Vicki Ho — who are both first-generation Asian Americans — decided to found “Banana,” a new magazine “dedicated to contemporary Asian culture.” The New York-based bi-annual title seeks to turn the misappropriated word into something celebratory by bringing together creative Asian talent from around the world to voice themselves."
