No, I just want to understand, WHO IS A RUSSKIY? From every corner comes a story about some rysskie, but how to define them in real life?

The land where russkiy supposedly live is Russia.
The passport of the alleged russkiy - Russian
The language of communication of the alleged russkiy- Soviet (Russian). Look up on the internet what russkiy looks like and how it differs from Russian.

So who are russkiy, how are they legally defined and where is their land? Or do russkiy live like homeless people: without their land and without a passport, and the word russkie itself is something like gender - it is only in a person's head?
