You removed Belle from the Crazy Characters category. The definition for that category is "Characters who are a bit mad but nonetheless have good personalities." Last time I checked, falling in love with what is technically an animal and not a human being is not exactly what one would consider sane, especially when she did so apparently without even deducing or realizing that he was a human prince cursed into a bestial form. In fact, Bestiality was actually considered a sign of insanity. Since she still had a good personality, yet was slightly insane due to falling in love with the Beast before even realizing he was in fact human, that category needs to be added back in. I'm not sure why you're against adding it in, as it actually fit the definition. At least be glad I didn't add her into the "psychotic villains" category.
Yes, those are one of the categories marked for deletion from the wiki. You see, there are several overly specific and flat-out unnecessary categories on this wiki, and several of us users have been going around deleting them, though some users constantly put them back, despite explanations. Though, this is the first time you're hearing of this, I'm sure, so this is different.
