Can anyone explain what racism is?

racism is the discrimination against somebody by the color of their skin (their race)

Explanation:

Racism is where a black/African person American is hated by a white person, or the white hated by the black/African American. This is sadly alot of racism in the world.

I tried to make it as simple as a could.

this is not a question its simply asking you to read and write a few sentences and   the question on the bottom its fairly easy, you can do this!

i see, would you mind putting it as one?
