Explain how you think the stereotypes created by the actions of people like john brown and characters in popular readings like uncle tom's cabin promote the coming of war.

Peoples actions are very important, there are several rasict sterotypes like white people are rich, black people are poor, mexicans jump fences, ect.
either way just remeber someone is watching so never do the wrong thing wether you think someone is watching or not always do the right thing. 
Example: lets say i'm black and i go and rob a store everyone will be like, "oh, well im not surprised, they always do that". (no rasicism intendeed, trying to do an example of a sterotype) - btw i'm white and black in real life - biracial
