Social Contruction of Reality in "A Bronx Tale"

In "A Bronx Tale," the neighborhoods and how things run are very different from the neighborhoods we live in right now. In the movie, it seems like most of the neighborhood runs around Sonny because he is the most powerful guy and people fear him. People will do Sonny favors just so he won't cause them any trouble. One of the unwritten rules put in place was that there was a dress code for the bar, and the bartender wouldn't serve the bikers because they weren't dressed appropriately. The bikers asked nicely but then they started causing trouble and got a mobster beat down. Also, the neighborhood is divided by race with the white italians on one side and then black people on the other. Each race is supposed to stay within their own "racial area" in the neighborhood or else violence occurs.
The construction of people doing things for Sonny came about because Sonny started working some mob things and people found out how powerful he was and they did favors for him, so he could do some favors back. He also helped keep the neighborhood safe from outsiders starting trouble. The construction of the division of races proabably came about because it was around the times of the civil rights movement and people still wanted to be separated because not everyone could get along. So racial attitudes caused the separation of the neighborhoods because violence would occur if everyone mixed because the italian kids tried to burn down the store black people's store where they hang out.
