Well, the whole left wing idea is based on the introvert side of a human mind. When Ted mentioned that minorities in developing world get excluded from society. My experience living in Sydney come straight through me: An old white man trying to greet old Asian man. The Asian man (generally reclusive and wary of strangers), didn't reply back, instead begin talking back in Mandarin, "Is this guy crazy? Speaking with himself?"
At best, it can be regarded as cultural clash. At worst, it is a good gesture not replied with a good feedback. Not inclusive? Yeah right... when in Rome...
Anyway, back to Russians. Well, they are friendly, if you know how to approach them. Basically, I would consider Russian social group as "family-oriented" one, together with the whole Mediterranean and Latin American culture. They are very closely bonded with their groupies and generally very shy among strangers. Every culture that has a bit of mafia culture (Chinese Triads, Japanese Yakuza, Italian Cosa Nostra, Mexican gangs, Russian mobs, etc etc etc) needs different approach to successfully engage with them.
