While some individual reports may be contradictory or even inaccurate, there is historical evidence from multiple sources that converge on one conclusion: That the Turkish government committed genocide against the Armenians. As with historical deniers in other areas, they grasp on to small contradictions as evidence that the entire event must be false.
The historical reports of the Armenian genocide accurate. They tell of the 2 million-plus citizens who were wrongfully murdered and evicted by the Turks. Although Turkish people have always denied the Genocide, the historians and bystanders have all recorded it into the annals of history. Perhaps one day the atrocities will actually be acknowledged.
The history of the Armenian genocide is an undeniable fact. The Ottoman Empire was able to kill many Armenians during World War I just because they were Christians that might side with the Russians. Hitler even later said that the genocide was real and used it as a lesson because the international community did nothing about it, which led him to believe that he could cleanse Europe of Jews.
Yes, the historical reports of the Armenian genocide are accurate, because there has been a great deal of genocide in the area. The victims are always under reported in a situation like that. Since there is some reporting that is accurate, there are likely many more victims than we are being told about.
I think that the historical reports of the Armenian genocide are accurate. I do not see any reason to think otherwise. A lot of the accounts are from reputable sources. I also think that there would be no way that such information can be manipulated for some reason or another.
