Respuesta :
Racism might still exist because people live in the past. Such as teaching their children to continue seeking their race as the supreme and better race over the rest. Some people might just be affected by one person from an entire race. Such as a shooting of a white person done by a black person. This can be seen as hatred towards all black people hated because of one person doing such a crime. (My opinion)
I don't really know maybe because we have different cultures and doings and not everyone agrees and then fights break out and this people hate that people and racism starts idk idk these are just my thoughts. Hope it helps though.
