To understand this intricacy, we have to browse the news papers and archieves of articles and comments of contemporary writers. Assasination of Mahatma Gandhi raise so many questions. It is ironical that a hindu fanatist killed the best hindu who recited Hey Ram! at his last moment. The RSS is an organisation , aiming at establishing so called Hindu Rashtra. They never respected the constitution of India. They never respected the tricolour of Indian nation. All these things are known in public domain. No member of RSS had any role in the strugle of independence. Assasination of Mahatma Gandhi also left a question mark on the efficiency and accumen of Vallabhbhai Patel, since he was the home minister at that time.
Nehru knowing full well that Vallabhbhai's failure in averting the assasination, asked Vallabhbhai to continue. Based on the information that he killer was a member of RSS in past and other reports of jubilation on the assasination of Mahatma, Vallabhbhai banned RSS. Later on the ban was lifted when RSS agreed to stay out of politics. Vallabhbhai was a true patriot with religious inclination. Other leaders like Rajendraprasad and Madan Mohan were also of this camp. Their views were not in line with Nehru's view. Nehru's views were of a rational secular benevolent to all religions.
If you see the reports during the passage of Hindu Code Bill, you will find that Vallabhbhai and Rajendra Prasad has opposed this proposal of laws only for Hindus. The other right wing organisations including RSS also opposed this. The popularity and stalwardship of Nehru resulted in Hindu Law. Vallabhbhai also opposed article 370 on Kashmir as RSS also opposed. These things bring Vallabhbai's view in line with RSS.
The BJP is a political wing of RSS. BJP wants to get power by whatever means. RSS, being a religious organisation, does no believe in democracy and secularism. They are trying to make all propaganda so that Nehru and Gandhi should be shown as villains responsible for partition of the country. They are also propagating a religious nationalism as true nationalism.
Vallabhbhai beloned to patel community. At present, the patel community is against BJP on the issue of resenvation. The assembly elections are round the corner. The party is using Vallabhbhai for wooing patel votes .
Anyway, all these efforts will not affect the views of common man for Gandhi, Nehru and Vallabhbhai.
