Yes, it is quite irritating to be honest. It's also a bit degrading to just categorize each of them as one person. -_- TWW Link is very close to me for reasons, so I get a bit uptight when it comes to this subject. He just isn't given enough respect in the Zelda community. Although, it's not like I don't entirely understand why this label is used. Ignorance? Just plain not caring perhaps?
But anyway, cheers for people who can actually tell the difference!
