I really appreciate your question. I believe most cultural stereotypes are based on ignorance. Therefore, to overcome these preconceived ideas, we must gain knowledge. Knowledge about other cultures will expose the truth and show that each person is an individual and most likely doesn't fall into a "specific" category. This knowledge can be gained best through a 1-1 personal experience with someone from another culture, travelling, immersion, or by speaking an universal language such as English. What do you think?
well, first of all we need to understand that diversity is a gift that God gave us, being aware of this and before we verbalize our humble and, several sometimes ignorant opinion, setting a good or bad label over one nation, it will be better if we start to search and learn more about the history and beliefs of one specific group, always being open minded, being respectful and looking for the roots of its behaviors, mainly those that we don't comprehend, if we do this I believe that we will be much more assertive and less prejudiced, besides give us the opportunity to see the world with another perspective.
of course we can and must apply this in our relationships to understand for instance, why some people are more methodical, while others are more introverts and sometimes less kinesthetics, likewise there are people who are more expansive, talkative and communicative.
