Ostracising ‘others’ is organically built into some societies.
The ghettoisation, which represents and visibly defines the communal schism between Hindus and Muslims, is itself result of deeply segmented self imposed societal compulsions we had lived in for centuries.
We had been observing ghettoisation in villages and cities where you can still find Brahim pada to Bhumihaar pada or Santhaal pada, Chamaar Dandi, Jain mauhalla to Gur Singh enclave. Even in hostel messes I had seen Jat mess, Jain mess, Andhra mess, Pahadi mess, at least we had that in college I studied. Communal segmentation is extension of that deep rooted malignancy.
Faiths and castes are similarly weighed for deciding relations, neighbourliness, even touchablity. It’s our collective burden. Secularism, the way it was broadly observed during first thirty years post independence, had started mitigating those negative ancestral values with visible impacts. We had started turning more concerned for basic needs and personal development than knocking the past for both validation and retribution as we experience today. Alas, We have quickly been falling apart now.
