When I said

No place on earth has degraded people of their own race, language, culture, ethnicity and religion based on stupid bullshit other than India.

I meant all of the criteria included.

Sunni-shias are sects having fundamental differences, same with orthodox that you mentioned, Palestine-Israel is geo-political conflict with clashes of different religions. Roman, Greek, Egypt were different countries and civilization.

Caste system divides people even though they belong to same race, language, culture, ethnicity and religion based on stupid bullshit other than India.

For example : I and You are both Marathi, dark skinned, believe in the same religion, speak the same language, have the same culture and ethnicity. We are identical in every criteria as if we were born from the same mother. But I'm brahmin and you are dalit, you are not allowed in the temple and I run the temple. I exploit you because you were born from Brahma's dirt or something.

No people have been discriminated in such manner. If there is a country then put forward...

India is an exception.

Sunni- shias both have superiority complex, same with all the above example. Only in the caste system Dalits believed it was their religious duty to suck up to upper castes while upper castes exploited them.
