Colorism

Why do darker skin blacks make fun of the lighter ones?  I don’t know why, but I at least know it is a form of racism. Just because they are mixed with black and white, does not make them not black or not white. I can see it, as it can be confusing for the teenager to be mixed. He or she doesn’t know what group they belong in a judgmental world. Your personal identity can be anything as long as you are ok with it. Socially everyone is always considered to be one race even though they are mixed. What those African American teenagers who are mixed are going through with the darker skins one saying they are not black because they are half white. That is racist to a degree to the white people as well.
