Poles are more blonde on average and have less rounded lids' openning for eyes.
Hm... you mean this specimen:
would be rather Ukrainian, and this one:
rather Polish...?
:)
Well, seems the closer we are, the more differences we see inside the nation. Slightly aside, and some more or less vague generalisation emerges.
Generally speaking it can't be an insult to call somebody a non-Slav. Though when deliberately calling a Slav not a Slav could be that.
But you just assume that Russians are Slavs by definition. Now what the definition is, except 'speaking a Slavic language'?
Not earlier than you prove me that the Poles are Slavs.
I started thinking about it right after posting, and no, I'd rather not. Can you think about a set of a handful of features that fit both a Russian and a Czech, a Pole and a Macedonian?
I suspect I know why Nathan doesn't think Russians are Slavs, but come on. Czechs are half German, Slovaks are half Hungarian, Bulgarians are half Turkish. Different history, different cultures, different religions, different mentalities.
