I must be a genetic nerd, I try to put my viewpoints based on the latest studies, but I don't take them as fact until they have been corroborated, that goes for Olade or Reich. Firstly there is no one is the world who is pure and unadmixed. There are people who try to prove genetic continuity going back deep in time like the Youtuber called Iran Talks who proves to his satisfaction that this is the case with Iranian groups while he does the opposite with Greeks and Italians. Today in Europe, certain nations are more native European than others, that have had less non European immigrants, and others that have more like France, Britain, Sweden, Germany. It is to be expected that in time those immigrants will be absorbed into the native European population, and then France, Britain, Sweden, Germany will be filled with off White people. Southern Europe was the place to be for hundreds of years, non Europeans moved there, and some were absorbed. In Italy, there was an Iran farmer Neolithic component present among the Anatolian farmers from the beginning, that Iranian farmer component increased during the Imperial Roman age due to immigration, but only decreased slightly to modern times. Now if modern Italians having more Iran farmer ancestry than other European makes them less European, well, too bad. Many of todays immigrants are not West Eurasian like those Iran farmers but South Asian, East Asian and sub Saharan Africans. Now what is better, what happened in Southern Europe in the past or what's happening today? BTW, I am not racist.
