Why SOME Israeli groups are so impolite and what to do? [closed]

I know this topic could be misunderstood and polemic, but I believe that everybody here is clever enough to understand my words and give good advices.

Last April, I came from a trip to Brazil. This is the third time I go to South America (Peru 2006, Argentina 2008 and Brazil 2013) and in all my trips I have had problems with Israeli groups. This time the problem was a very impolite use of the shared hostel room (smoking inside the room, music at 4am, etc). Obviously it's not a "prejudices" problem, because I didn't know they are from Israel until I speak with the hostel manager. She said that this is very common and she always try to not mix Israel people with other travelers.

And the most important, what to do? This time I talked with the management and they tell me to move to another room. I did, but I would like to avoid this situation in my next trip before it happen (and no, to use a non-shared room is not an option :) because in Argentina the problem was during a 8-hours bus trip).

EDITED to ask only one question: I don't understand this behavior but I would like to know what to do to avoid contact with impolite groups of Israeli people in South America.

First of all, I think you did good when you said SOME in your title. This will save your question from being closed ;)

Second, in some areas of the world smoking in public places and indoors is tolerated unlike Europe and speaking loudly or making noise in the middle of night is just ok, such as in the area these group came from. People from these areas and some other areas around the world who do not travel a lot tend to behave the same way as they behave back where they live. I think if you talk to the management and the management talks to them they will understand and will stop this. I do not recommend you talking to them because this could lead to some unexpected reactions from such groups, including physical and verbal assault.

One more thing, these kind of experiences are to be expected for travelers, you can not expect everybody to perceive the same behavior as polite or as civilized as you do. Enjoy :)
