While the Russian kids were playing by the rules (at least not significantly outside of that) especially the British kiddos did everything they could to win the medals we received in these games from the hotel.
So what does my anecdata tell us? Nothing. I have great experiences with Russian people while I was cheated by Brits. Should I deduce all Russians are great people? Or all Brits are cheaters? Probably would be a bad idea.
There clearly are different cultures. But talking about that as if this means people a a homogenized blob of that culture does not pay justice to the people who went to the streets in Russia to protest against the war for example. Or to the people that only know the propaganda side of this war on any side.
