Why are americans racist

Most Americans are racist because of White Supremacy. Back then, they were superior for being white, since Native Indians' land was stolen, their women were rap3d. The Black people were slaves, and their women were also rap3d. So mainly, the reason why they considered themselves superior was because they were able to rap3 women, children, & men without them being able to have a voice to defend themselves.
