At least 31 percent of white Americans held racist views according to a IPSOS Poll that was conducted online from Aug. 21 to Sept. 5, 2017. Extrapolating this using the entire white population hopefully will allow you to see just how much of a potential threat racism is. According to United States Census projections there were 248,503,000 whites in America in 2017. If thirty-one percent of the white population held racist views, that means that there were potentially 77,035,930 whites with racist views living in America at that time.
Contrast this to the projected 2017 American population (323,128,000), and potentially 23.8 percent of the American people held racist views. That is basically one in four Americans.
