This BBC documentary is by no means an isolated incident. It's part of a tradition going back more than 2 centuries much after the Battles of Plassey & Buxar cemented British rule in India followed by their right to taxation of the Bangal Suba which included present day WB, most of BD, Bihar + Jk & Odisha. After Buxar those rights included Awadh as well which meant most of Central & Eastern UP.
The riches thus accrued is what fueled the industrial revolution in UK & in India as they would subsequently discover they had not only a rich source of raw materials but a market for their finished goods too.
This rapidly changed their attitudes from one of wonderment to disdain & thus crept in racism becoming entrenched in their thought & beliefs, becoming part of their educational curricula. It's from here you have the white man's burden, the McCauley plan to do away with all native systems of education & institutionalize the Western model of education based on a curricula they created which was designed in a manner to be in awe of Western achievements & to be ashamed of anything native as it was inferior which resulted in our enslavement.
All these neo Ambedkaridite movements, the Dravidian movement, McAuliffe Sikhs, separate electorates & preferential treatment for the Muslims stem from this thou process which was fine tuned over a period of 1 ¼ - 1 ½ centuries after which we gained our independence. As you may note we're still grappling with these very same problems a full 75 yrs after independence & partition.
Now this clip in question which I've shared is part of the same mindset where the interviewer - an American is literally demanding answers from a hapless Pt Nehru about Muslim representation in our government, civil services , the academia & the armed forces among other fields.
All this, after knowing the reasons for partition . But you would never see the same interviewer take to task the rulers in Pakistan where the native H&S were practically genocides from W Pakistan & in what was then East Pakistan now Bangladesh a series of ghastly riots from the partition riots downwards right up to the 1971 genocide where the vast majority of those killed & raped were Hindus to the present day where a population of ~ 20% + H in BD at the time of the 1951 census is now reporting > 8% H with a falling TFR & reports emanating from BD itself about the eventual disappearance of Hindus from BD by the end of this century. Compare that to the situation of Muslims in India today & do note at the time of the first census in 1951 they were > 10% of the population & if the census were held today they'd easily be 17-18% of the population.
Why is this clip important? For the sheer timing of it. This clip was recorded between 1962-64 for it shows Nehru in a very haggard state as a result of the stroke he suffered following the 1962 debacle. Around this time, India was veering towards the USSR as the US was fully backing Pakistan though things changed for a brief period during the 1962 war.
In the event for all the answers the American interviewer is demanding about representation of Muslims in various institutions in India, there was the Civil Rights Movement launched by Martin Luther King in the US to demand basic rights for the African American.
This is what institutionalized racism is all about.
I'd post more clips from different sources with this same theme of institutionalized racism, a feeling of superiority, colonial hangover etc which still pervades most of the UK which is why Paddy's casual racism isn't or shouldn't be surprising at all. It comes from a certain set mindset cultivated over generations & centuries. Part of it was responsible for Brexit too.
