No, man, Catalan isn't all that difficult, there's just no point in learning it unless you're going to live in Barcelona the rest of your life. And even then everyone speaks Spanish too. I speak Italian and French and I can sometimes translate entire Catalan sentences (I have two friends who are from Barcelona and they speak Catalan amongst themselves). My knowledge of Arabic grammar is very basic, but as a European I'm pretty confident it would be much harder for me to learn Arabic. I also don't believe we're any more capable of learning a new language, it's just that we speak a lot of different languages and that most of those languages have similar grammar.
