Tribal does not equal backwards. Lest you forget, the Prophet of Islam was also a tribal, as he belonged to the tribe of Quresh.
The term as you use it is extremely nebulous, as is your understanding of the 21st century… What exactly should one adopt as a part of the 21 century, for such a person to fit into your definition of being 'enlightened?"
If I wear 21st century clothes, am I tribal then? What exactly does adapting the 21st century mean?
I think the term you are getting at, however unsuccessfully, is “JAHIL.” or Dufur.. There is definitely a lot of Jahaluth in the world, but its certainly not synonymous with tribal societies.
You just use the term “Tribal” because you like how it sounds. But I honestly don’t think you truly grasp what the term means or what it implies.
