What causes racism?

"Racism is one of the most revolting things within the vicinity of humanity. It haunts our past, many times degrading the future". one of the most common causes of racism is stereotypes, this is because the people see through television, radio, and movies. When we are young we are exposed to people that are shown in this stereotypes so we think that they are bad, or they will behave in a way that can damage us, like in the movies. Another cause of racisim is unfamiliarity, this is becaue people fear what they do not know. Selfishness is another key factor in racism, this is because humans are selfish creatures, because they only care about there own expense. Another big cause is enviromental factors, our phisical envioroment can affect our biology and that can affect our minds. These are all the causes of racism, and because of racism people dont get to know all of the persons, you can get to know a lot of people from every race who can get to be a good friends of yours, and that you can get to share with alot, race doesn't show how a person could be. In conclusion movies, tv shows, radio give a bad stereotype of all the different races, every race has virtues that people dont account for, and this is why the human race it is not perfect. Because the person who thinks bad of another person its not a person that you should be around with.
