Racism can be backed a long time ago, from the colonial era's. It has been a thing among humans to be racist against some sets of people. We have heard of many cases when black or Africans are treated as trash just because of their skin differences. In the ancient times, black people are treated as slaves amongst the white and their lifes had no value. Racism can result from, skin differences, religion, culture, languages, beliefs and many more.In the world today though racism has been lessened with the introduction of some human right activist and some other laws Against racism. Some countries or persons still practices racism. So I don't think racism will ever be a thing in the past. It goes on and on till the end of time.
