Educate yourself on the ways of cultures different from your own. If not for any other reason than to understand others, and maybe yourself, a little better. The more of us who do this, the greater the benefit to humanity. Open your mind and even critique your own culture, modifying your beliefs and actions to achieve a more understanding, well rounded, and compassionate world view.
I am fortunate enough to have met people in many parts of the world. People of different races and cultures, people from different socioeconomic backgrounds, people with different religious beliefs. I have worked and conversed and traveled and shared meals with them, and what I can say with complete honestly is that I have found reasons to like them all.
