Terming religious conversion a silent invasion, Karnataka Chief Minister Basavaraj Bommai on Monday said the menace of conversion should not be allowed to grow in society. "Hindus were often invaded leading to large-scale religious conversions from time to time. If you see people from other religions around us, they were originally Hindus. Besides the geographical invasion, there is religious invasion happening in the country. If geographical invasion happens openly, religious invasion happens slowly," Bommai said during an event organised by the Vishwa Hindu Parishad.?
