Here's a quote from it that has been there for months.
Ranma is quick to use insults, intimidation and/or violence when dealing with those who upset him, typically worsening the problem instead of solving it. Using diplomacy, money, or blackmail seems too complicated, or in the last case, dishonourable for his tastes.
I'm not sure about the Anime version of Ranma but that entire paragraph is wrong if going by the manga. Ranma is not quick to use insults. He doesn't insult people until after they've insulted him (not counting accidental insults and when the others insulted him first -Akane who insults him as if not more often also insulted him first multiple times and Genma who insults Ranma often). I don't remember Ranma using intimidation against anyone but Nabiki in the manga (she countered by sticking a cat in his face). Ranma has attempted diplomacy on multiple occasions with Ryoga(into), Ukyo(into), Mouse (time Mouse dated the statue), Taro, etc... Ranma would use money to solve his problems if it could the reason he doesn't is because no one other than Nabiki wants it, he doesn't have a lot of it, and he did give Nabiki money once in the manga. The reason he doesn't use blackmail is simply because he doesn't have much to blackmail the people with. He did try and blackmail Nabiki at one point (found a letter to Kuno while searching Nabiki's room thought it was a love letter) and tried to use it to blackmail her into giving incriminating pictures to him. Also he sort of uses Ryoga's curse to blackmail Ryoga (threatens to drop Ryoga into water while Akane is around).
(I've tried to improve it but someone goes and change the stuff I put when I do).
He takes great pride in his prowess as a martial artist and openly brags about it whenever he has the chance.
That's also on wikipedia. When does Ranma brag about his prowess? Sure he'll occasionally say he's the best and down plays the assistance of others but I don't remember him bragging to others. In fact I remember the exact opposite in which when asked if he does martial arts he modestly said "a little". I don't even remember him talking about any of his battles. He does brag about his physical looks though.
Another thing it mentions Shampoo as being his fiancee but isn't Shampoo technically his wife by her village laws not a fiancee. (she always calls him husband, Cologne calls him son in law, etc..) They just want Ranma to accept the marriage.
Another thing I was wondering not exactly related but is the ghost cat in volume 20 the same ghost cat that was in volume 14? Personally I'm thinking that it is a different cat spirit. Reason I think that is because Akane was surprised by it, it did not recognize Ranma and Akane, uses a different means to get girls, and the first one was scarred of Ranma because Ranma injured it while in the Neko-ken.
