Murder by a mob and such activity is illegal under 9th century shariah that is used in Pakistan (typical for Muslim countries–even though Muslims love to propagate their religion in free non-Muslim countries) for such matters. All that said, is Pakistan your example? Basically everywhere, including in all advanced countries, there is a freedom of religion and part of freedom of religion entails the right to be able to promote your religion.
It is senseless to compare the situation of minorities in India with that in Pakistan. Discrimination is written into the laws of Pakistan (more disturbingly, there is no significant movement among Muslims to change these laws…); in India the two most powerful leaders are religious minorities (A Sikh and a Christian Catholic). In Pakistan it is illegal for a “kafir” to become prime minister or president.
