Which is racism?

Despite all the modernity experienced by societies today unfortunately is still common to find cases of prejudice and discrimination because of race differences. In theories of law and practices of everyday life, racism is an attitude that must be abolished, buteven today, many people do not know what is. So it is good to clarify some doubtsabout what racism is.

Racism is not a scientific theory but a set of preconceived opinions where the main function is to enhance the biological differences between human beings, which some believe to be superior to others according to their racial matrix. The belief of the existence of superior and inferior races has often served to justify slavery, the domainof some people by others, and the genocides that have occurred throughout human history.
