English! Do you speak it!English?

It would more commonly be said this way

When I began my journey I thought English was spoken in every corner of the world and everyone should speak it, but with the passage of the yearsime, I have changed my mind, ​i. In fact, I have learned that one must make an effort and learn at least few words or expressions of the country in which you are living.

Very often I have come across a fact that really annoying fors me; American people want them to be spoken in English only, no matter the country in which they are in.

The sentence flows better this way

I have met a lot of people from other nationalities, and very often the language we used to communicate was English, but sometimes during a conversation with someone whose English wasn´t the mother tonguemother tongue wasn't English we tended to use words in other languages most of the time.

"Sometimes" and "most of the time" in the same sentence feels a little contradictory but also redundant

Often, the context or a further explanation makesde the meaning of that word clearer, and we were available to have a mutual understanding.

It really doesid not matter if the word was in German, French, Italian or another language we always tryied to understands each other. However, there is a particular population who apparently does not share this mutual convention, Americans!

Using past tense to match the rest of the text

Even if we are in a country, where English is not the official language, it´s very common to hear them utter “In English, say it English” just like if it was an order!

I think that is the reason why Americans are seen as extremely narrowed minded people.

To reach a mutual understanding is when two people have differences of opinion and compromise until they come to an agreement.

It turns out, wWhen an American joined a conversation with people from other countries, they get really get offended when someone uses a different language raother than English while speaking!

Even if we are in a country, where English is not the official language, it´s very common to hear them utter “In English, say it English” just like, as if it wasere an order!

Over the course of the years, I have joined conversations where people constantly switch from one language to another without any problem nor any prejudice, b. But when it comes to Americans, the story is totally different.

Probably my preconception is biased, but until now, my experiences have proved to me the contraryn me right.

This is tricky; "conception" is the wrong word here. "Preconception" means inherently biased. Or you could say "my perception is biased". I think "My opinions are probably preconceived, but up to this point my experiences have proven me right" sounds best.
