::You have failed to give a single rational argument for not including ethnographic maps, only a rather shrill WP:IDONTLIKEIT.  Only you object to the them.  Why are you so hysterically opposed to including the maps?  What are you afraid of?  How do they confuse our readers?  They do not confuse our readers, they inform our readers about the ethnographic composition of the Balkans at the time, thereby providing valuable context.  You are the only one who objects to the presence of the ethnographic maps, so if you want to pursue dispute resolution with yourself, go ahead.
