You are using your intuition of the past instead of any actual knowledge of such to formulate views and values. Yes, the Mongol empire was extremely tolerant of cultures by any interpretation of the word. For instance at the time religion was a huge deal and while himself a shamanist, he exempted all religious leaders (of any sort) from taxation and public service requirements. He also built a wide array of houses of worship for most of every major religion. With religions that proved troublesome to integrate, such as Islam, the Mongol leaders would themselves genuinely convert to the religion to try to help maintain better ties and relations. In places were there was religious persecution, Genghis Khan would happily depose leaders (including other Mongols) to ensure freedom under his empire. Outside of religion they also even allowed local leaders to remain and organize their subjects as they saw fit (subject to things such as guarantees of religious freedom) including even maintaining their own militaries. The only requirement was a 10% tax to the Mongol empire. They way he spread his genes was pretty much as the way we do today. The only difference is that he had hundreds of wives. Take somebody with several times the wealth of Jeff Bezos today and make him the absolute ruler of the USA, EU, and China. And now he imagine he asks, genuinely asking - not an offer one cannot refuse, practically any woman on this Earth to be one of his wives. Very few would say 'nah, I'm holding out for somebody better.'
