He said former Home Minister Sushil Kumar Shinde in the UPA regime had questioned Hindu terror in a very different context but Singh's statement was a completely diversionary argument.
Chidambaram said Shinde made a statement outside Parliament and did not use the phrase Hindu terror in the manner in which Rajnath Singh was quoting.
"What he (Shinde) was referring to was the right wing extremist groups and some of them were charged in several bomb blast cases, Malegaon, Mecca Masjid and one or two other cases.
Chidambaram said Shinde had questioned Hindu terror but in a very different context where he was contrasting the other terrorist groups, which owed allegiance to some other religion.
"But I don't think he branded terrorism as Hindu terrorism. I think Rajnath Singh is completely distorting the statement," he said.
