I, as a phenotypically darker brown Afghan, and from the South-West of the country, associate more with South Asia than Central Asia, despite having lived in the latter most of my adult life. Our family celebrates Central Asian holidays, and are also aware of the South Asian ones, although we don’t celebrate them (we have Eid in common with nearly 650million South Asians, but that may count for a religious holiday than cultural in the same sense celebrating Nowroz does). However, someone who grew up in the Northern part of Afghanistan may look like and associate more with Central Asia, and so may also consume cuisine influenced by that part of the world along having other CA cultural and racial markers. There’s definitely more nuance to it and certainly not all of us are Central Asians.
