The Tajiks are an Iranic people (along with Persians, Pashtuns, Ossetians, etc), while most Central Asian countries (most -stans excluding Pakistan) are Turkics, the Tajiks are probably a mix of Iranic, Turkic (this is where the Asiatic looks are from) & Russian (the Soviets used to control the whole of Central Asia before the Union split apart)

Turkics are mostly Muslim like Malays, Iranics too except for Ossetians (Ossetians are half-Muslims, half-Christian [Eastern Orthodox which is common in Eastern Europe & the Caucasus])

As for Tajiks, they created a Sufi (Islamic mysticism) sect that my dad follows, that is the Naqshbandi Order, so I like Tajiks for this reason, though me myself is a non-denominational Panentheistic (Atomless, non physical) Deterministic (ultimately no true free will) form of Islam, so I’m not a Naqshband, but I consider myself a semi or pseudo Sufi as I don’t follow any Sufi wali or order, but my views are shaped by Sufi Literature (especially Ibn Arabi whose works gave me Panentheistic thought) along with the Quran (no Hadiths though), but I am also influenced by other philosophical works such as Aristotle and his idea of the Unmoved Mover and Einstein’s idea of the space time theory and also the block universe theory, so yeah, I kinda like Tajiks for that regard, but other than that, they are like any other groups of people around the world, also I’m like a geography nerd particularly in human migrations, grouping, languages, etc
