Now, my theory of what it means to be a Fairy-type is to be a Pokemon associated with "light." This can mean literal light or good in the circumstances given. Generally, as seen in the show and the game itself no Dark-type Pokemon is inherently evil (excluding Darkrai) so as such Fairy-type's aren't inherently good either. Granbull can be seen as a prime example dipping into both the Dark and Fairy movepools and as such supporting my previous theory. To be more thorough though I wanted to take a look at a peculiar scenario in Pokemon-typing below.
Togekiss is 1 of 2 pokemon labeled the Happiness Pokemon along with the Normal-type Blissey, but why didn't Blissey's typing change? I dwelled on this for a while thinking it went against my proposed theory, but then I read the X/Y entry for it stating: "Its eggs are enough to bring a smile to anyone's face." This in my mind translated to: the happiness it's associated with comes indirectly whereas Togekiss's does not. This would explain why Togepi's line was retconned to Fairy and Happiny's wasn't, because none of the Happiny lines are associated with light and now the happiness they spread can be seen as indirect and not inherent.
Okay, that was a lot to type, but I feel it was necessary.
Do you all agree with the theory, if not can you poke holes in it? Let me know below, and remember this is strictly my interpretation. You are welcome to agree, disagree, debate, and criticize, but please do so politely.

Fairy is associated with magic, not "light" ( and good god let this light type stuff die already).
Fighting is an honorable type, and that is why it is good against dark. Fairy is good against dark and fighting. Fairies are not "the good" type looking at that. It makes no sense for a good type to be good against an honorable one.
Fairies are supposed to be based off of mythological magical creatures, often shown in fairy tales. Their magic is good against dragons, like a lot of fairy tales.
Fairies are often shown as being tricksters in fairy tales, not necessarily good/light.
The hole in you argument is that you don't have one. You provided very little basis for your theory, just what you believe.
