It is sad to see that Indian Society, specially youth is still a pre of Sangh Parivar's Propganda.
My many friends were member of SIMI. No doubt, they had very strong concepts which are not general in the nature.
And yes they wanted to promote their concept. And a democratic system give everybody to do the same.
I personally dont believe that they were the part of any Bomb Blast or something like that.
I saw them in West Bengal, UP, tamilnadu serving the poor people. They were very calm and friendly for any individual who meet them but Yes they used to see all the Govts around the world as corrupt govts and they wanted a public movement.
I also do not agree on some points with them but it doesnot matter bcz i believe that everybody has the right to express his feeling in a great democracy like India
