Let's pretend everyone was colorblind, even though white people were the complete opposite of anyone Africans had ever seen, but let's pretend anyway. White people were understood to come from a different part of the world. They wore different clothes, they had different accents. Even without race, they were clearly distinguished from any African people. Many Africans had similar clothing, ways of living, accents, and a certain familiarity with each other. They lived side by side since the beginning of time. White people were strange and different, more different than anyone else. When African people saw these foreign men caging and shackling other Africans, they never thought "that could be me"? They didn't realize that foreign men were taking all Africans, no matter what tribe, country, etc.? These foreign men were taking women and children. What crimes did those women and children commit? This was nothing like African slavery. Were white people taking tribes, or were they taking Africans? It shouldn't have taken long to see that they were taking "us." And once that realization set in, it should've horrified people to see what they were doing to "us."
