I agree totally with what you say. If you were to travel back in time to 1950 and to walk into inner-city Detroit late at night, you would probably get beaten up. If you were to travel to the future to the year 2100 to inner city Minneapolis late at night, you would get beat up also.
They’ll never change.
In 1950, if you were black and walked into a suburban diner, you would get your a$$ kicked too.
Things were different in 1950.
