the problem with that is their perception of "islamic shariah" vs your perception thereof. It differs. while they are trying to bring their ideology of islamic environment and shariah, they cannot promise jamat islami people their understanding of islamic shariah, or ghamdi follower their ideology or alike.. So the issue will boil down to.. you have what you have on your plate.. who do you pick.. if its PTI for now.. then rest the case and hope for best. Perhaps get in touch with their personale to get your views accrossed but dont expect him to wholly accept your views, otherwise you might as well stand in his place.
