Culutral Differences or Discrimination?

What separates human beings from animals are the intellect, power to reason, and the mind-the greatest work of God. Their nature, instincts, feelings, emotions and desires are all the same. For sure, the apparent differences in mankind are only for identification as to who are European, Asian as well as African. Yet a great cultural barrier separates them bringing a significant contrast between them. Living in different parts of the globe, the respective eastern and western people are quite unsympathetic to each other.
It is this cultural aspect of life that is the inspiration behind the book. Is this a cultural difference, attitude or intolerance? Hence the book evolves all these essential and vital issues of life.
