The only reason comes in my mind that you dont want to evoke anger in others; when you as a person invite them to join or convert to Qadiyani faith. but the official view of Jammat e Ahamdiyaa is that all other muslim sects are Kafir.
Peace inuit
Surely this is a good thing that the Ahmadis do not want to get people angry. We should try it out as well. Of course we should tell the truth but only when asked directly otherwise other things take priority but only in dawah.
