The original set had Colorless (Normal, Flying, Dragon), Fire, Fighting (includes Ground and Rock), Electric, Grass (includes Bug and Poison), Psychic (includes Ghost), and Water (includes Ice). They eventually added "Metal" and "Darkness", if I remember right. Not sure why those were given different names, but whatever. As far as I'm aware, there never was a Dragon type in the TCG, unless it was introduced quite a bit later.
If you actively hate Justin Bieber... then you don't know what "intended audience" means. Hate Twilight instead, it's far worse.
