According to Nicholson, encounters between explorers, such as Christopher Columbus and Henry Hudson, and Native Americans were always friendly. There was no "expression of hostility based on physical appearance" (Nicholson 15) between the two groups. When there was any hostility, it was not based on physical appearance, but rather more of culture practices or values. Cannibalism, for example, "seems to take place without any regard to race, creed, or religion." In another case, Nicholson mentions that during the Crusade, about ten thousands Jews were massacred by Crusaders. It "was a religious slaughter without racial implications." (Nicholson 26) Through these examples, we can see that Nicholson suggested that race is not scientifically valid because people did not judge others based on physical appearances, but the notion of race is mainly described by one's skin color or hair texture. Nicholson's arguments coincided with modern scientific views, which conclude that race doesn't exist, due to the fact that DNA inside people with different skin color and hair texture is 99.9 percent similar. Therefore, the notion that race is biologically constructed in invalid.
Social reality of race simply refers to the fact that people still believed that races are based on physical traits such as skin color or hair texture to judge others. However, what they are doing is stereotyping which lead to discrimination and racism. Also, their actions
