THIS is because of the secularism.our constitution has given the ideas of  equality,fraternity and brotherhood . it was ancient time when the leaders would  come from communities. our india is a democratic country . and it has proclaimed itself as a secular country.secularism means that there will be no role of religions , community in the work of the pakistan has announced itself as a muslim country and there are no rights for other religions . but our india doesn't want to misbehave with the other religions.
