Or is it because many people feel a bit uncomfortable with English being the language of the most imperialist power on earth.

So true. English being the international language just becomes an excuse not to learn another language. I love learning new languages, especially helpful when you are traveling.

I heard about Esperanto and I met some people learning this language during my travels . Now without the verb conjugation, irregular tenses and plural, it might be easier for me to learn Esperanto!
