How High caste hindus treat low caste Dalits in India

So enlighten us because we have no idea. Clarify instead of hiding it.

Hinduism would be incomplete if you take discard certain things, wouldn't you agree?

Bhagavad Gita does not talk about divisions?

Why do international organizations addresse the Daalit problem so much?

So, why not remove the caste system and treat everyone equally?

Take a snapshot of that page where every search result links to Pakistan & share it with us, because I barely found any, hence your point is invalid & irrelevant to the topic at hand.

How drastically? International organizations still complain about this problem in India and do not mention much about it decreasing.

There may be discrimination in Pakistan, but certainly not pertinent to tribes. Tribes are used to identify ethnicities, like India has many Parsis (immigrants from Persia) and Pakistan has many Mughals (Persian-Mongloids) - both are types of tribes that trace back to another locality, and both can often be differentiated from others by their physical attributes.

In the Bhagavad Gita, Ch.18, verse 40:
The Lord says:
"There is no being on earth, or again in heaven among the gods, that is liberated from the three qualities born of Nature."

Gita Ch. 18, V.41:
"Of Brahmanas, Kshtriyas and Vaishyas, as also the **
*Sudras, O Arjuna, the duties are distributed according to *
**the qualities born of their own nature."

Gita Ch.18, v.42:
"Serenity, self-restraint, austerity, purity, forgiveness
and also uprightness, knowledge, realisation and belief in
God are the duties of the Brahmanas, born of their own nature."

Gita,Ch. 18, v.43: **
"Prowess, splendour, firmness, dexterity and also not
fleeing from battle, generosity and lordliness are the duties
of **Kshatriyas
, born of their own nature."

Gita,Ch. 18, v. 44:
"Agriculture, cattle-rearing and trade are the duties of the Vaishya merchant class), born of their own nature; and action consisting of service is the duty of the Sudras (servant class), born of their own nature."

Gita, Ch. 18, v.48:
"One should not abandon , O Arjuna, the duty to which one is
born, though faulty; for, all undertakings are enveloped by evil, as fire by smoke."

What do you make of this verse:

Gita, Ch. 18, v.48:
"One should not abandon, O Arjuna,** the duty to which one is **
born, though faulty; for, all undertakings are enveloped by evil, as fire by smoke."

I will agree with you on one point, that people corrupted the concepts for their own interests.
