Even if theism is a failure, it's still superior to atheism

[Jehanne]

Among certain historians, there has been a recent movement to rehabilitate the Mongols, which is the view that you are presenting (defending?); in my book, they were/are mass murderers, even if they lived in an era of mass murder.

But what you are doing is trying to paint them as worse than other conquerors of their time, a view only ever propagated by racist European and European descended propogandists.

Mongol Empire

Quoting Eric Margolis, Jones observes that in the 13th century the Mongol armies under Genghis Khan were genocidal killers[37] who were known to eradicate whole nations.[38] He ordered the extermination of the Tata Mongols, and all Kankalis males in Bukhara "taller than a wheel"[39] using a technique called measuring against the linchpin. In the end, half of the Mongol tribes were exterminated by Genghis Khan.[40] Rosanne Klass referred to the Mongols' rule of Afghanistan as "genocide".[41] It has been estimated that approximately 11% of the world's population was killed either during or immediately after the Turco-Mongol invasions (around 37.75 - 60 million people genocide in Eurasia, out of which at least 35 million deaths were in China).[42] If the calculations are accurate, the events would be the deadliest acts of mass killings in human history.
The second campaign against Western Xia, the final military action led by Genghis Khan, and during which he died, involved an intentional and systematic destruction of Western Xia cities and culture.[citation needed] According to John Man, because of this policy of total obliteration, Western Xia is little known to anyone other than experts in the field because so little record is left of that society. He states that "There is a case to be made that this was the first ever recorded example of attempted genocide. It was certainly very successful ethnocide."[43]

Tamerlane

Similarly, the Turko-Mongol conqueror Tamerlane was known for his extreme brutality and his conquests were accompanied by genocidal massacres.''_at_Wiki: -44][44] William Rubinstein wrote: "In Assyria (1393–4)—Tamerlane got around—he killed all the Christians he could find, including everyone in the, then, Christian city of Tikrit, thus virtually destroying Assyrian Church of the East. Impartially, however, Tamerlane also slaughtered Shi'ite Muslims, Jews and heathens."''_at_Wiki: -45][45] Christianity in Mesopotamia was thereafter largely confined to those Assyrian communities in the north who had survived the massacres.[46] Tamerlane also conducted large-scale massacres of Georgian and Armenian Christians, as well as of Arabs, Persians and Turks.[47]
