No, I agree with him. Everyone knows Russia has territory inside Europe. Does that make it European? Post-Ukraine not a lot of people would call it European. It's just a word at the end of the day, the politics are more important to people that geography since both are made up. Why does Europe end at the Ural mountains? Because we said so.

Why is Europe a separate continent? Its one big land mass.

Show the world map to a child and one would have a difficult time explaining the idea of continents when they finally come to Europe and Asia.
