Nobody is promoting English. The brute fact is, people all over the world demand to learn it.
All we do here is try to accomodate the many requests for assistance in learning English.
I can understand your sentiments, and I don't think your question is unreasonable.
Most languages are beautiful in their own right. However, all the same, it is convenient for us all to be able to speak with each other, and sometimes this is easier when there is a single language that so many of us can learn.
English may have been very difficult to learn in the past; but with modern technology, such as Television, Internet Live Chat, and recordings in speech broadcasts and Music, it is very easy for so many people to acquire a working knowledge in basic English.---Warm Regards, Bruce
