:*Mosque is well defined in its main article Mosque. What more do we need? It's a place of Islamic worship, where Muslims pray 5 times a day. The removal of the certain mosques is mainly because many Muslims do not consider Ahmadis to be Muslims and hence their place of worship are often referred to as anything but a mosque by those Muslims. This is why there so much antagonism to the list of mosques belonging to the Ahmadiyya Muslim Community. That's the actual issue being raised here. 
 :*However removing those particular lists or separating them from the rest of the mosque list in order to comply with many Muslim's opinions would in my opinion result in discrimination. Hope that helps!
