Perspective on inter-religious understanding - Hinduism and Islam

Most of the Hindus as well as Muslims are just and hard working people.

However, each one of their religions has a fundamental problem right now.

Hinduism: The philosophy as well as practice of division of the faithful in castes are insufferable poisons. The scriptures should be revised to correct the untenable postions related to this aspect.

Islam: The fundamental intolerance of other conceptions of God -inherent in Quran and Mohammad’s life - should be unequivocally repudiated and the Quran edited to cleanse it.

There are various ways of achieving this:

Eliminate the people who resist, Spread secular education to neutralize the poisonous teaching, Abandon the entire rigmarole of religion and adopt the scientific philosophy.

My belief: Working solution probably shall contain each of the above elements.

The question is: In what proportions?
