Delivering a lecture yesterday, the minister said social harmony and development would be "in danger" the day the population of the majority community starts decreasing.
He said nationalism was in a "kind of danger" due to demographic changes.
"...Democracy is safe in the country as long as majority (Hindu) population is there. The day the population of the majority community starts decreasing, the democracy, development and social harmony will be in danger," he said at the lecture on nationalism here.
He said a family planning law for all faiths should be enacted.
"...With all responsibility, I say that the social harmony has taken a beating and nationalism has declined (in areas) where the population of Hindus has declined," he said.
