All the examples you are citing are valid, except that this all happens to ordinary Russian all the time and hundreds times more, but the media never reports on it, because Russian lives don't count for the Western media.
So many Russian owned businesses were shaken out by non-Russians, people robbed and killed, scammed out of their money, thrown out of their own apartments by the muslim immigrants. How many Russians kidnapped by Chechens in broad day light in Rusisan cities.
If the situation in Russia is so bad for non-Russians, why do those afriacan and arabs students keep arriving to Russia in larger numbers. You would not go to Zimbabwe or South Africa, knowing the situation their, would you?
You say - "Almost every Russian friend I have, including my wife at first until I taught her how bad it was to say, refers to blacks by the "n" word."
Well, I guess you have not heard blacks talking on the streets here in USA, saying all kinds of racist things about white people, and calling for extermination of whites:
"... We have to exterminate white people off the face of the planet ..."

"30 black teenagers from Marine Park Middle School, most of them girls, chased five white girls from St. Edmundâs off a Marine Park basketball court and across a Brooklyn streetâpunching, kicking, slapping, pulling hair and screaming, âhonky bitches,â âblack powerâ and âwhite crackersâ"

And while we are on the topic, this is what muslims do in Sweden to local Swedish teenage grils:
