On quora the learned people there have qouted sources and links if you had cared to go thru it.
As for Sardar Patel he was first and foremost a lifelong Congressman, a Gandhian and a secular person who abhors your RSS. Also he was in full agreement with Mahatma on making Nehru ji PM. Gandhiji decision was also proved right as Patel died in 1950, three years after independence. Whereas Panditji continued to serve the nation till his death in 1964.
Also every sanghi like you must remember that it was your beloved Sardar Patel who banned the RSS soon after the murder of Mahatma and called it a very dangerous organisation for the country. If it was not for liberal kind hearted Nehru ban on your RSS would never have been lifted. He asked Patel to lift the ban. Go learn history 101 before shooting from the hip, though it is very difficult for radicalized brainwashed people to learn anything.
