>I doubt that I am the one who must learn English here. The phrase "Americans like cheese" certainly does not mean that all like cheese. There's no difference here between our languages.


The phrase "Americans like cheese" is a stereotype, which is "A generalization, usually exaggerated
or oversimplified and often offensive, that is used to describe or distinguish a group." according to
Dictionary.com.

In this case, you grouped ALL Americans together with your statement "The Americans can be soo childish
in their behavior.". This mans, and is taken as, "All Americans are childish in their behavior", which is an insult.

So, maybe you ARE the one to learn English.
