RACISM

Racism is the belief that characteristics and abilities can be attributed to people simply on the basis of their race and that some racial groups are superior to others. Racism and discrimination have been used as powerful weapons encouraging fear or hatred of others in times of conflict and war, and even during economic downturns.

Racism is also a very touchy subject for some people, as issues concerning free speech and Article 19 of the Universal Declaration of Human Rights come into play. Some people argue that talking about supporting racial discrimination and prejudice is just words and that free speech should allow such views to be aired without restriction. Others point out that these words can lead to some very dire and serious consequences (the Nazi government policies being one example).

CULTURAL IDENTITY

why we need an cultural identity ?

because, other people will recognize us from what communities we belong to, and it contributes to a persons's overall well being. 

Cultural identity is an important contributor to people’s wellbeing. Identifying with a particular culture helps people feel they belong and gives them a sense of security. An established cultural identity has also been linked with positive outcomes in areas such as health and education. It provides access to social networks, which provide support and shared values and aspirations. Social networks can help to break down barriers and build a sense of trust between people, a phenomenon sometimes referred to as social capital.

However, strong cultural identity expressed in the wrong way can contribute to barriers between groups. And members of smaller cultural groups can feel excluded from society if others obstruct, or are intolerant of, their cultural practices.
