Arey bhai, I don't mind if Pakistanis consider me kafir. But don't claim to have the exclusive right on Islamic terminology etc. Or kill Ahmadis, or destroy our mosques. Rest you can write ahmadis are kafir and tie it around your neck for all I care. It's not the declaration of Kufr that is much interest to me, it is the hypocritical persecution by Sunnis who on one hand cry if Europe or anywhere else persecutes their fellow believers but leave no stone un turned in their vigour to persecute those who have differing of opinion in their countries.
Besides, a loooong time ago I explained on this very forum that Ahmadis believe in different degrees of Kufr, this was explained by the very person whos quotes are posted on anti Ahmadi websites in his sermons during his own life. None the less, it is a religious topic and one that I'd like to avoid as I've seen well enough what happens here.
And also we will not stop you from calling yourself Muslim, if someone says he is a muslim, then who are we to say he is not. So even if Pakistan was an Ahmadi majority state, there would be no laws etc declaring Sunnis or Shias to be kafir.
