@Raghu & Baasha: Thank you both for taking the time to share your views on India and its future. My question is: In India, is the caste system specific to one religion? In other words, are the untouchables only Hindu or Muslim? Is the caste system only followed by Hindu's?
Thank you!
The "caste system" is universal. It is spelled out in Hinduism because it is in nature. An "untouchable" is anyone who is adharmic (not following Dharma). If you're of low birth (not Indian and Hindu) and not part of the 4 castes (Brahmin (scholars/priests), Kshatriya (warriors/statesmen), Vaisya (merchants/businessmen), Shudra (laborers/servants)), you're technically an untouchable. This is why it is laughable when westerners think they are somehow "above" the caste system when they themselves are the untouchables they want to "protect". The "Indian" part seems strange but every Hindu in India, should be able to trace their lineage to the 7 sages of Aryavarta (ancient India). Anyone who falls outside of that is called a "mleccha" or barbarian/untouchable.
Caste is of two things: VARNA & JATI. The first is based purely on philosophical grounds and is derived from three things: lineage (birth), character, and action. None precludes the other. Jati is based on occupation and that is what is most prevalent in Indian society today. For example, farmers' children tend to become farmers. Doctors' children tend to go into medicine etc. etc. This is where it is universal.
When the two (Varna & Jati) are used interchangeably, it is highly dangerous and can lead to severe discrimination and ill-treatment of others. This has what has happened for the past 200 years in India. So-called "high caste" people used their "high" birth to legitimize ill-treatment and denial of opportunity.
Caste is highly misunderstood by most people and interestingly, MadWand1 has touched upon it somewhat accurately. Obviously, he has read a bit about Hinduism (?).
One thing that has to be made absolutely clear is that people who convert to Islam and Christianity have NOT escaped discrimination by Muslims and Christians. In fact, there are a lot of Muslim and Christian "Dalits" (untouchables) who are not allowed to mingle with others in that society. The anti-Hindus will clearly leave that important fact out of the picture.
In fact, Muslims have a severe "caste" system within their own "brotherly" religion. Muslims from the subcontinent are treated like trash during the Hajj pilgrimage in Mecca by Saudi Muslims who fancy themselves "closest" to Muhammad. In fact, Pakistani Muslims look down on Indian Muslims and actually call them "ajlaf" (converts into Islam) while they think of themselves as "ashraf" (supposed foreign ancestry). In fact, this was one of the biggest reasons Bangladesh (used to be East Pakistan) didn't get along with West Pakistan because of this attitude as well as language (Urdu vs. Bengali).

And, for discrimination against Christians converts (Dalit Christians), look here:

The proper name for "caste" is Varnashrama Dharma. Gandhi himself supported it. That shows that it was most certainly NOT to divide people but to make people realize their true potential and strengths and work for the betterment of the society as a whole. It is the antipode of individualistic thinking as that is the basis of Hinduism; realization that the ego (individual "I-ness") is false (impermanent) and that the real "I" or Self is non-different to the unmanifest reality [Brahman or GOD].
Jati is followed by everyone around the world. Varna is more complex but it is also universal.
