There are better things to do than construct temples. For instance: a. Most of the corrupt in India are Hindus. So why can't they stress that corruption is anti Hinduism and anti Ram Rajya? b. Most of the streets are dirty. So why can't they stress that cleanliness is Godliness? Why can't they lead by example and clean up the streets? c. There is a big gender inequality in sheer numbers. So why don't they target all the doctors who do abortions on girl babies? d. Most traders sell adulterated goods. So why don't they protest at all these traders? Do all this, then you will achieve Ram Rajya
