[EDIT: Ironically, had a grammatical error!]

Fluency in English is the only thing that matters in today's world.

Anything that hinders your ability to speak it at the highest level possible (e.g., learning other languages) is a mistake.

CLARIFICATION: What I resent is that English is not my first (and preferably only) language.

You're looking at it wrong. English is the closest thing we have to a human lingua franca. I hope you're not bashing it for nationalistic reasons, because, even if it owes its ubiquity to an imperialist past, English today is the property of its non-colonial speakers as much as its native speakers.

You will appreciate this oddball pseudo-germanic, latin-esque language when you venture out of its home turf: I tutored English to Arab students who were learning it to communicate with Chinese manufacturers, and a Vietnamese musician who wanted to reply to his Myspace fans, including a Thai girl who has a crush on him :-D

Try to love whatever culture and language your parents gave you, for starters, regardless of their utility or perceived social stature.
