Let me put forth some facts about the organisation called RSS right at the beginning.
- RSS is a social organisation. There is no formal registration and participation is completely voluntary.
- It is not a political, religious or profit making orgnisation.
- There are no posts, there are only responsibilities (in fact that what they are called).
The Sangha cannot force anyone into not believing in the caste system since it does not control any individuals thoughts. However, it certainly practices non-discrimination. For example, I have been to a shakha which is like a grassroot level proceeding of the sangha. Here I have taken instruction from a non-bramhin, had food with, bathed, prayed and lived with lower caste individuals. It is what I practiced as a swayamsewak. The Sangha will not issue a diktat or a fatwa. It will merely preach by practicing. So more the number of people who start going to a shakha the more they will stop believing in the caste system.
Go through the facts I have mentioned about the Sangh and you will realise it is no different from Orkut...but the sangha comes with a purpose, with an ideology and with some discipline.
To sum it all up, RSS is as biased as Orkut, when it comes to an individual's caste. :-)
