"Since terrorism is a matter relating to the country and not to a community, why secular leaders remain silent when all persons arrested in terrorism cases belong to a particular community," he told reporters here.
"Are there only a few to define religious non-discrimination? Is it not true that all the terrorists caught belong to one community? I am not saying that all the people in that community are terrorist but whoever is caught belongs to same community," he said.
The BJP leader, who was recently booked for his hate speeches, said this mindset was "posing a danger" to the country.
"This is a naked example of pseudo secularism and patronisation of a community for vote bank politics. This mindset is posing danger to the country," said the Nawada Lok Sabha candidate of the saffron party.
During the poll campaign, Jharkhand and Bihar police had lodged three FIRs against Singh for saying that those opposed to Narendra Modi had no place in India and they should go to Pakistan.
"A terrorist is a terrorist, he has no religion, no caste. You can bring the NIA list of those who have been caught as terrorists. If they are found to be of one community, I will say that they are of one community.
"A terrorist belonging to any community will remain a terrorist, not a patriot. Terrorist is a terrorist whether he is a Hindu or a Muslim," the BJP leader said.
Speaking on the issue of Article 370, he said, "Our ancestors had incorporated it in our Constitution. They did very well. It was probably done for socio-economic welfare of the state, but today after six decades, Kashmir's economic and social conditions has not improved. The country is supreme, a referendum must be done on whether 370 is needed or not".
Targeting NC leaders, he said "Farooq Abdullah says that those who vote for Modi should drown in the sea. But Farooqji, you have pledged over the Constitution, you are a minister in Indian government, why your voice comes to a halt when Pakistan tears our flag and your government watches quietly".
