Today I met a very old amrithdhari about 80 years old. He suffered greatly during 1947 partition. He said that in 1947 RSS was active in Punjab and had a membership of atleast 1 lakh people.
They were the first ones to kill Muslims in what is today Indian Punjab and when the train carrying dead bodies of Muslims reached the Pakistan Punjab, they thought that these killings were done by Sikhs and as a result starting killing Sikhs and thats how the bloodshed started.
