Yes well you see ahmadiyya is true religion because of its bileafs too. We bileave in the promised messiah to have come to guide Muslims to right path not any new teachings just like it says in Islam. The promised messiah also gave us real proof he's true messiah. The Quran says holy prophet may peace be upon, that he is the final messenger and seal of prophet which means he's the final person to bring new teachings, the promised messiah did not bring new teachings, he only guided Muslims to the ones that already are. Also look at Sunni and Shia, they divide into so many movements. Sunni have like salafi, etc but ahmadiyya only had 1. You could say we have 2 sects but not really since we don't work together with them like you guys do with your Sunni movements. There is ahmadiyya and Lahore ahmadiyya, Lahore Ahmadiyya just don't bileave in khlafat like normal Ahmadi people do and there such little number of them too today. We are not Lahore Ahmadi though, ahmadiyya and Lahore ahmadiyya are 2 different sects since we don't work with them.
anyways let's talks about Sunni Shia and Ahmadiyya. Sunni Shia and their all movements work together to eliminate ahmadiyya and even kill us in Pakistan which is not following teaching of Islam.
And the reason I said we are fastest growing religion in the world Is to ask the disbileavers why Allah would help us Ahmadis so much if we're false religion
