This is the way I see the fans of different ponies
Fluttershy fans: Probably the most sensitive fans. We protect Fluttershy because she's so vulnerable and we would hate to see her get hurt. We are fairly annoying though
Rainbow Dash fans: They're like the cool kids of the Brony community. They watch the show cuz they genuinely think it's not a girl show (which it is).
Pinkie Pie fans: They watch the show cuz they want to have fun and they get a kick out of funny, cute things.
Applejack fans: I'd tell you about AJ fans, but I have yet to meet one :/
Twilight fans: The polar opposite of Applejack fans. THERE'S TOO MANY! I now know how non-bronies feel, because Twilight fans are taking over the community just like bronies are taking over the Internet.
Rarity fans: Rarity has best fans. I think we can all agree on this.
