He also blamed "vested interest groups" for spreading the panic on the issue of reservation for Dalits, saying it is done before every election and asserted that the government will do everything to protect their rights.
Right from the day the apex court gave its judgment on the SC/ST atrocities act, the central government acted in an "immediate and informed" manner and has filed an effective review petition to protect the Dalits' rights, Shah said.
He pointed out that Prime Minister Narendra Modi had met MPs belonging to the Scheduled Castes and had assured them that the government was doing everything to protect the rights and wellbeing of "our Dalit sisters and brothers." Through the Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Amendment Bill, 2015, the NDA government had actually strengthened the provisions of the Act and this was in line with the BJP's commitment to the welfare of the SC & ST communities, he said.

"Due to the politically driven manifestations of a microscopic minority of dejected and rejected political parties, crores of innocent people suffered. These parties owe our Dalit sisters and brothers an apology for their misdeeds," he said.

The BJP is locked in a keen fight with the Congress in the Karnataka assembly elections, scheduled for May 12.
"The BJP's stand is clear, which I am once again stating - we fully believe in the Constitution given by Babasaheb and the rights it has given to the SC/ST communities. At every juncture and in all possible ways, the BJP stands shoulder to shoulder with the Dalit community," he said.
The Modi government's commitment to fulfilling Ambedkar's vision was unwavering and all its efforts were aimed at transforming the lives of Dalits, Shah claimed.
Attacking the Congress for "mocking" Modi's DNA, he said the party had defeated Ambedkar in Lok Sabha polls twice and made "flimsy excuses" to ensure his portrait was not placed in Parliament's Central Hall.
It also denied him a Bharat Ratna, he said, claiming that India had seen through its negative politics.
Congress chief Rahul Gandhi had said in a tweet that the DNA of the BJP and RSS was anti-Dalit.
Shah said, "We will continue our efforts to make our Dalit sisters and brothers the makers of New India. We will fulfill their aspirations and dreams. Jai Bhim! Jai Hind!"
