Most people assume that the rise of Pakistani boxers in the UK came out of just interests but if you were to further dive into the reasons. You will begin to realize that it was white and black people who were teaming up in the national front days and the days of Enoch Powell that led to many Pakistanis joining gyms to protect their areas.
Even though this is referring to Bengalis in Tower Hamlets when they were East Pakistan.
Monty Neysmith- Jamaican black skinhead said that Pakistanis in the East end, in 1969, which is basically Bengalis there because Pakistanis from Pakistan did not live in the East end were regarded as "passive" and " weak" race

Have you noticed that when black people get abused, its seen as blacks being racially harmed and hurt due to white racism in the American psyche
However when South Asians were attacked by both white and black skinheads, they were regarded as a weak race who couldn't fight back
Notice black men weren't emasculated for always being abused by white men but South Asian men were seen as "passive" and "weak"
However this racism was restricted to areas of London
When whites and blacks came to the north where real Pakistanis lived, for example, Paharis, Mirpuris, Pashtuns and Punjabis, then they were overwhelmed and attacked. If you look up the Bradford riots, white skinheads started it and Pakistanis ended it, then look up the Lozell riots, black men started it and Pakistanis ended it.
Even Naseem Hamed the Yemeni boxer started boxing because the far right skinheads were attacking the guy in Sheffield as well because he looks brown skinned.
Its a whole different world now, almost every Pakistani male can fight, they're not like their grandfathers, actually even Pakistani grandfathers could fight too, look up the Lynx gang, but they didn't have the technique and hands of modern Pakistani male fighters, even street beef videos have so many pakistani men man handling black males and white males
Look up Dennis the Menace for proof in UK King of the ring which is the UK version of street beefs.
Remember Pakistanis, and South Asians in general, never let whites and blacks call you weak. We come from a land that fought the British in multiple wars. Even the Anglo Afghan wars were fought on Pakistani soil and those were Pashtun Pakistanis. However even Sikhs fought white men in the Anglo Sikh wars
South Asians just never had unity, South Asian men were always better fighters than white men or black men in history if you look at their encounters on an individual level.
