the McDonald's add that is re-writing history?

it doesnt say what USA state that advert takes place in, it may well take place in Illinois or California, where McDonald's started, there was little or no widespread racial discrimination in these states in the 1950s.

jim crow laws/segregation only happened in southern states like Alabama, etc.

Black people were denied seating on buses and entry to many restaraunt's and other amenities in the USA up until the 1960's when they rightly started the civil rights movement's fronted by Martin Luther King and the likes of Malcolm X, there was much overt & covert discrimination against black Americans throughout that country.

Having said that there were still parts of the massive country that is the USA where by 1955 black people were seen as equals to any other race and it is therefore perfectly feasible that the scenes in the advert or like them did take place in 1955.

There is much erasing and skewing of true history by todays Mainstream media outlets and such as the BBC placing black people in historical British drama when during such times black people were still in Africa or held positions no higher than that of a slave.

It definitely airbrushes history - mixed race couples in the US (even in enlightened California) would have caused raised eyebrows. But more importantly, McDonalds and many other outlets enforced segregation in many states and were among the businesses picketed in Greensboro during the civil rights marches

I remember Muhammed Ali or Cassius Clay as he was, said he was world champion but he had to come to the UK to eat in a top restaurant..

Definitely suspect.
