When I say Qadiyanis should be respected as human beings it means they must not face any violence and live peacefully as citizens of Pakistan. Giving them respect doesn't mean we can't return what they give. They show hostilities towards our faith by suggesting that Quran is incomplete, Muhammad's guidance is incomplete that's why another Prophet (Mirza) was required. These hostilities are considered as direct assault on Islam which is based upon teachings of Quran and ways of Prophet Muhammad peace be upon him. In this situation, Qadiyanis can't be considered friends of Islam but are regarded as enemies to Islam. However we don't believe in oppressing our enemies as long as they don't carry on with their attacks. Confining them and their activities through constitution and law is necessary for both their safety and of others in our country. If there's no law to limit their activities there will be bloodshed between Qadiyanis and other citizens of Pakistan.
Anyway, if you are here to advocate a case of Qadiyanis, this is a wrong thread. This thread is talking about a religio-political case with regard to Imran Khan and his party.
