Just learn whatever language you like. Language skills are not any sort of reflection of whether someone is an intelligent person or not. Hundreds of very knowledgeable people who are completely illiterate. It just means they didn't learn a certain skill and weren't exposed to that specific learning environment. Not that they're any less of a smart person. Besides, languages are just manmade words, sounds, and letters that large groups of people decided to adapt as their own. If you like the language, learn it. If not, and you don't like the culture, don't worry about it.
