::::::::It sure is tiring. As I said in my first reply, this is not an article about Indo-European studies or about the PIE homeland. We have other articles on those topics, including the Kurgan theory and the Renfrew theory along with others. They ach have separate dedicated articles. This is an article on the history of the concept of an "Aryan race". I'm sorry you find that difficult to understand, but it's rerally not so hard. Historians like Polaikov and Arvidsson are the appropriate WP:RS for discussing this historical concept and its influence.
