Let's look at this in two cases.
1) Michał, Sergey, and Jamala didn't only get votes from the diaspora. Then how is it their fault that people in Western Europe liked their songs?
2) Michał, Sergey, and Jamala did only get votes from the diaspora. Then how is it their fault that they were the only ones who actually voted in large enough numbers to push themselves to the top?
How about a mix of the two? If the diaspora votes are substracted from the total and only those who voted for the songs because they REALLY liked it remain, Ukraine and Russia would still have ended very high.
And if most votes came from the diaspora, I don't blame the artists at all, I blame the diaspora. That doesn't take away that Russia's song is still annoying and Poland's extremely boring.
I study Russian in university, and like a Russian football team...
I apologize, I didn't know that.
I speak fluently English with an American accent, and admire the USA in many ways, I also know quite a bit about their geography, history and politics.
Would it be ok if I dispayed an American flag above my avatar, even though my nationality is Belgian.
