Let me redpill you OP.
What you’re referring to as slavs, are in fact, ruthenians/eastern germanic descendants of kievan rus, or as I’ve recently taken to calling it, east nordids.
Slavs are not a race unto itself, but rather another component of the ethnogenesis of the scandinavian norse germanic people from the migration of the peoples and onward, made historically relevant by the kievan rus settlements in Gardariki by the norsemen who traveled down the Volga and founded both Russia and Ukraine before being christianized by the byzantine empire.
Many eastern germanics speak the artifical glagolithic church language invented by the greek monk Cyrill, which is where the term cyrillics stems from. Before that, they spoke old norse and revered pagan germanic gods.
All the so-called "slavs" are really descendants of eastern germanics. There is objectively no argument to be made against this historical fact.
Thanks for reading, and please refer to them as "eastern germanics" next time you make a "slav" thread.
