Hah! Slavs aren't 'white looking'--there's an old Russian saying: Scratch a Slav, wound a tartar. Look at Lenin and those mongolian features.
The Russians are Slavs. (Strictly speaking they are the eastern mixture of Varangians and Slav, the western mixture are the Ukranians and Belorussians)
As for Vladimir I'lich "Lenin" Ulianov, he was at least 1/4 Volga Bulgar. His maternal grandfather was a Bulgar and Lenin was born and raised in what is now the Chuvash state.
The Magyar were probably the progeny of the caucasoid xiongnu coming back west to trade in europe.
Language doesn't work.
