The same can be said about Russians (tatar+slavic+mongol mix)
What's "Russian" in your book? Are there only the ones who are "tatar+slavic+mongol mix". How about the Russians that do not fit these composition? Who are they?
Look at the current mayor of Moscow - he's considered white in Russia but for western people he looks kinda alien.
He is white, though not a Russian (unless he wants to be so for he's raised in Russia, his mother tongue is Russian and adopted the Russian culture).
Their mentality is not too european I'd say
Does being European equal to being always right in your mind? You're a confused teen I'd say...
