Even among non-fascist Mongolians there is veneration and respect for Genghis Khan as a semi-mythological figure, the same way there is respect for figures like Barbarossa in German culture, and Alexander Nevsky in Russian culture. Bands like The Hu, who admittedly slap, have made many songs venerating Lord Temujin. Batzorig Vaanchig has a traditional mongol song venerating Temujin that has 13 million views. Which also admittedly slaps. Veneration of Genghis Khan in Soviet era Mongolia was treated as reactionary and somewhat discouraged (some say "banned" but I'm not sure), however, from what I understand, traditional attitudes towards Temujin (Genghis Khan) inside of Mongolia view him as sort of a founding father figure and ignore a lot of the violence he perpetrated. They focus on his early life where his father was assassinated, and his family was abandoned by a larger tribe and he and his mother and brothers were left alone to fend for themselves in the wilderness. He was kidnapped and taken as a slave, but then escaped. Then he married into a richer tribe but his first wife Bortei was kidnapped. He rescued his first wife Bortei, and then met up with his childhood friend Jamukha. He and Jamukha worked together to unite the tribes into a larger confederation, but became enemies. Temujin defeated Jamukha and became Genghis Khan. Genghis Khan then expanded the Mongol empire after uniting all the mongol tribes that had previously been separate from one another. He reformed military practices and created a "meritocratic" hierarchy where people without noble blood could be promoted, which was considered "progressive" for 12th century Mongolia. Looted wealth of victim nations was also redistributed amongst the Mongolian military, rather than simply going to the top, creating a strong incentive to enlist and stay loyal. Also he "rescued" Uyghur Muslims from Jin Dynasty rule (lol) and integrated them into his empire, and got Uyghur scribes to develop a system of Mongolian writing, since Mongolia prior to Temujin didn't have a system of writing. He also got them to write his biography, which was kept secret for many generations after his death. Also his empire was somewhat tolerant of religious diversity and did not force Temujin's traditional Mongolian religion Tengrism onto others. But yeah. He also looted and raped and pillaged and took sex slaves and catapulted diseased bodies into besieged cities. So not a good guy. Conservative and fascist Mongolians whitewash the bad parts and emphasize the "good" parts, like fascist Americans do with their founding fathers.
