Issues with minorties

Without a doubt America is built on the murder of natives and black slavery. For over 200 years blacks have been enslaved and for roughly about 100 years blacks have been segregated until the 1960s. De facto segregation may have legally been changed but there still is de jure segregation (separation by culture and socially).  Especially in the southern states, blacks and other minorities are separated and there is general hate between the races.  For example, in Alabama, a majority of white students have succeeded in the vote to not have blacks in school clubs and frats. This was just last year. The racism in the 1920s was far worst against blacks and even white immigrants (italians. jews, russians etc).

Following the civil war there were dozens of accounts of blacks fighting back, but it was a white mans world and a white mans country. Following the Tulsa Riots in the 1920s (riots against blacks and lynchings) lynchings increased even more due to white supremacists and the Ku Klux Klan. Even the North was racist, so following the riots whites stormed into black towns and cities and which leaded to many burnings, lynchings, lootings, and many killings. This led to the phenomenon of "white flight." 

White flight took place when very poor black communties got tired of the treatment in the South and migrated to major cities in the North expecting a better and more settle life which turned out to be the opposite. When blacks moved the whites took a "flight" and moved into the suburbs and left blacks in the inner cities which still leads to huge poverty problems even till to today. When blacks are left in the cities with no money, it leads to huge unemployment, horrible housing, poor education and funding, poor medical care, and hate between blacks and whites. You can still see these problems in modern cities, even Denver, That's why the farther you get away from the cities the lighter the skin is for people. 

Following white flight gangs were created not only because of prohibition but the invention of more drugs after 1920. Prohibition created organized criminal gangs all around the country and in every race,  You can still see the impact of slavery, segregation, and prohibition still to this day. Racism is alive and well but not as bad as the 1920s and the following decades. Whites, blacks, and people of all races are still looking for a solution to these issues but time will decrease the violence and hate. Hopefully one day, the races could exist peacefully in the US and not repeat the mistakes and treatment of people in the past. It is undeniable what whites ancestors have done and justifiable the hate blacks have towards whites.
