The Chechens are literally Caucasians. And from the European part of the Caucasus. They don't look any Asian at all. (Kadyrov's squinty eyes are because he's so fat.)
They also fight on both sides.
The slogan predates the formation of fascism as an (Italian) ideology.
It's for the enemies, and also its ignorant as it doesn't work that way. (Similar to the Russian practices in Chechnya. In reality doesn't matter what the enemy does to a Muslim's body, if you really can't be buried within 24 hours god also won't fault you, not least because it's insha'Allah after all.)
And the Ukrainians have literally nothing against Asians. They even like the Chicoms, more so than we in Poland, and twice more than the Czechs for example, and much more than the global median - with least dislike among ALL the countries polled, including Russia (https://www.pewresearch.org/fact-tank/2019/12/05/people-around-the-globe-are-divided-in-their-opinions-of-china/).
That was before Covid, of course.
Maybe you confused Chechens with Buryats. Hundreds of them have been killed and there are only half million Buryats.

They portray the Buryats as Mongols, and I fact the Buryats are Mongols.
South Koreans also have traumatic historical experiences with the Mongols.
(Mongolia doesn't care and celebrates Genghis Khan as the greatest national hero.)

I don't know where you had idea of Asiatic Chechens. There are some Asiatic groups in the Caucasus but they're Mongol remnants and aren't idniginous.
