City with a ridiculous and morally backwards culture, that has an overwhelmingly large amount of ignorant, narrow-minded, and racist people.
If you are colored, the white people won't treat you for who you are, but for what you are. Many of them are malicious in this sense, and enjoy the feeling and benefit of feeling superior to those they look down on, and sometimes wish to mistreat. Many white people (men especially) feel uncomfortable around colored people whose personalities do not fit within their knowledge of ignorant stereotypes, and have the tendency or desire to put down, intimidate, or mistreat a colored man who is confident, intelligent, and most importantly charismatic. If you are a colored woman, you are "allowed" to be a person, and assert an individuality, without it being rejected, because the white men do not feel threatened by colored females, and rather see them as desirable.
Nonetheless there is to this day an overwhelming amount of people who, pathetically, are still unused to or unfamiliar with the notion of colored people being people, and who still feel uncomfortable when a colored person enters the same restaurant, sits or stands nearby, offers their opinion, asserts their personality, or in general, is present. Perhaps they don't feel that colored people should have the same freedom to enjoy life. It is a sad example of the cultural denial of freedom and democracy in a modern American city.
If you really think this is untrue then take the time to stop and observe the world around you.
If you don't like an ignorant, narrow-minded and racist society, don't go to Chicago. This, is why New York is better.
