I can say from experience being mixed white and Japanese I’ll always be a second class citizen there.

Can’t speak for Russia but I knew a woman who once said she envied her mother because she was “pure”, pale skin and blonde hair, while she had dark hair and more eastern (Mongolian heritage?) features. That was really painful to hear someone say about themselves and if it’s the prevalent attitude I wouldn’t assume I’m welcome just by a blood connection.

The MitreSmiter 9000. Puts all doubt to rest.
