From your language it seems that you are totally against of RSS. Have u ever been to a RSS sakha? What do you know about their ideology? Do not go with what Congress or Mayawati say. I advise you to first go to any nearby RSS sakha and participate in their activities for a few days. Tell them about your cast...you will find that no one will discriminate you on the basis of your cast and if you think that RSS is anti muslim than also watch that how many times they make any plan or discuss to kill any muslim. RSS is a patriotic organization...every Hindu is welcomed without any sort of discrimination. They dnt go to any muslim and Christian to ask for conversion...but they are always ready to help a human being without any sort of discrimination.
