Why is the word "negro" so heavily used in the new Doctor Who episode "Rosa", isn't the show supposed to be PG? Using the word "Negro" makes it seem too violent for a PG show, plus using the word "negro" and yelling at a dark skinned person seems quite MA rated for Doctor Who.
It is used because it is an accurate portrayal of things that would have been said at the time in that area, although it has likely been toned down a bit. The actual words used were likely more offensive but to give an accurate portrayal the Doctor Who writers decided to tone it down a bit whilst still keeping the effect.
Remember that it was only in 1955 that Rosa Parks famously refused to give up her seat and segregation was actually still legally enforced in Alabama at the time.
On Thursday, December 1, 1955, Rosa Parks, an African American seamstress, boarded a city bus in downtown Montgomery and sat one row behind the whites-only section. As the bus filled with passengers, the white driver ordered Parks to surrender her seat to a white man. Parks refused. Her defiance prompted the driver to summon the police, who promptly arrested her for violating the city's segregation ordinance.
In the mid 1950’s, segregation was widespread and legally enforced throughout the American south. Birmingham, Alabama was a hotspot of black activism in opposition to segregationist policies.
Further "negro" was used in the newspaper reports of Rosa refusing to give up her seat and so it seems rather accurate to me.
The episode is clearly set in this time period and location and so the words used are certainly because those sorts of words would have been used.
Montgomery, Alabama, 1955. The Doctor and her friends find themselves in the Deep South of America. As they encounter a seamstress by the name of Rosa Parks, they begin to wonder whether someone is attempting to change history.
Remember that Doctor Who is also supposed to be somewhat educational and so it makes sense to have some resemblance of an accurate portrayal. In fact this new season is supposed to be more educational then the last seasons.
The idea, apparently, is to make Doctor Who more educational for its younger audience, as was the plan when it launched back in 1963, and according to new reports in the Mirror the series may have as many as three episodes set in the past, with another three in the future and four on present-day planet Earth.
