6and answer the question.
if a white girl reported that a colored man had made improper advances to her-even if the charge were unsupported and based on nothing more than a neurotic imagination-a white-sheeted band might spirit the negro off to the woods and "teach him a lesson" with tar and feathers or with the whip. if a white man stood up for a negro in a race quarrel, he might be kidnapped and beaten up. if a colored woman refused to sell her land at an arbitrary price which she considered too low, and a klansman wanted the land, she might receive the k. k. k. ultimatum-sell or be thrown out. klan members would boycott jewish merchants, refuse to hire catholic boys, refuse to rent their houses to catholics.
what is the best definition you can infer for the word "arbitrary" from the excerpt above?
