Racism: Why does it happen?

Racism? Hmm, first of all, do you know, what is racism or racist? According to Wikipedia.org,

Racism is the belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race. In the case of institutional racism, certain racial groups may be denied rights or benefits, or get preferential treatment.
Racial discrimination typically points out taxonomic differences between different groups of people, although anyone may be discriminated against on an ethnic or cultural basis, independently of their somatic differences. According to the United Nations conventions, there is no distinction between the term racial discrimination and ethnic discrimination.

That is just the term and why such thung can be happen? Well, what I think is, maybe due to the economic and social status of certain ethnic contributing the factor of this problem. People nowadays, like to judge people from what they have such as, where they live, how rich are they, think white colour is better than black and so on. This will create gap to the affected people. They will feel disappointed, sad and need improvement. When they not achieve what they want, the people will mock them again and again. Lately, they don't care with that people anymore and we call such incident as RACIST. Hmm, I've found another source said racism maybe due to fear. Well, what kind of fear? Fear that the strangger will take you house, your job and so on. You don't know who is that stranger and that person also didn't know us. Peer pressure maybe can be the factor of this problem. Well, I think that all for now. Stay tune with my blog and say " No To Racism!"
