The horrific colonial racist slur 'Paki' is still very common, although its well known by those who use to be extremely offensive. It is used extensively by white youth but also African heritage youth against those they consider are Asian, especially South Asian. When African heritage youth use the P word, they do it often knowing that their own family member(s), a grandparent or great grandparent or some other direct family member(s) is of Indian heritage usually from the Caribbean. It's actual use is a weird mix of knowing it is off limits but it is used anyway quite a lot against Asian people, and sometimes against other peoples who people wrongly assume are Asian/South Asian.
The lack of teaching and understanding that there is a massive Asian/South Asian presence in the Caribbean and the cross-fertilisation of Africans who were forcibly taken there and the Indians who were less so forcibly but forcibly taken there too by the brits, is a gap and something we have to fill and celebrate that unity of the two peoples in a new land, albeit a stolen land on whose native people genocide was committed by the european colonialists.
And then we come to the upsetting but interesting case of racial slurs against our Somali community, Somalis and East Africans seem to confuse people who have swallowed colonial racism, lots of complex things I am not going to go into, but basically our youth attack Somalis (generally not Muslim youth from Africa or Asia, but they do sometimes as well) on the basis that they don't look what is the stereotype of a 'Black African' phenotypes (physical appearance), they are also Muslim, many of them look quite similar to South Asian people, so the slurs against the Somali youth from other of our youth includes 'Abdi' (meaning slave, it actually is often used in names as in slave to the most high, but like paki which means pure/real thing/true, it has been warped into something disgusting), also Walahi (literally: by God), sometimes these two words are used together as a slur 'Abdi Walahi'. Racial slurs against Somali are the most acceptable out of all of them.
There is SO MUCH to say about all of this, but the bottom line is that this is all evidence that a considerable section of our youths (and adults!) have fallen into the most obvious colonial and imperialist divide and rule ploy. These colonial divisive strategies are becoming more effective and more pronounced in the work of the british state, and its arms such as the bbc, media and schooling. I don't see anyone talking about these issues and addressing and countering them. In a context of brexit/trump and growing fascism, the western states are deepening their divide and rule, and in so-called radical circles these divisions are being spun as radical by the colonial identity politics industry.
In a lot of these 'radical' circles there is a lot of anti-Muslim and anti-Asian prejudice being spewed and spun as some kind of radical posture, its not, its just internalised colonial divisions, they come straight out of the centuries long english colonial handbook. There is much less anti-Black anti-African prejudice in radical circles, although there are still major issues here in terms of addressing (I mean lack of addressing and appreciating) African liberation on the continent, and the role of African people as their communities are developing in the 'west'. SO MUCH UNITY building to do in the face of much more divisive colonial nonsense being internalised and coming to us directly from the imperialist ruling classes.
