Dear Compatriot!

You've made a reference to Article-260 of the constitution (but not to article 25 which protect equality of all citizens), under which Ahmadis have been declared as minority. But you're missing one important point that there is a clash of beliefs between the Ahmadis and other Muslims, So disfiguring the belief system of any religious community is strictly prohibited and one must respect the belief system of other communities. So think about it that who're the first comers the Ahmadis or the other Muslims. If the other Muslims were the first then Ahmadis must not have injected new ideas or have disfigured the already existing belief system of Muslims. Analyse this thing and think about it you may get a correct answer for your question.

Good luck!
