I'm glad that somebody else knows about the caste system. It is truly horrible. In an earlier comment there was reference to India being an 'honourable' country. The caste system is ingrained in India. While there are more enlightened minds there, this enlightenment does not always extend to those in the so-called lower castes. Frankly I detest it.
If India really wants to take a big step forward and show something to the world, it should thoroughly get rid of the caste system. But, as I just wrote, it's ingrained there.
