Sorry, but no. That’s like saying “It’s bigoted of you to say you enjoy this party at the gay club, because there aren’t any straight people here. After all, it’s also bigoted if someone says, they enjoy a party, because there are no gay people there.”
You need to consider US-America’s position of cultural hegemony. US-American culture & cultural products completely dominate most of Europe. In many European countries “national film” is it’s own genre, because the vast majority of films shown in cinemas are American. In some countries the “national film” genre takes up about as much space as the “foreign film” genre in the US. (France being a huge exception) The same goes for national or national language music.
If you turn on the television to any commercial channel, you will most likely see a US-American show.
It’s not like that’s necessarily a bad thing. I’m not complaining. The US can churn out cultural products at a much faster rate than the rest of us and they do flood European markets, but Europeans also want to see Breaking Bad and The Big Bang Theory and the next Hollywood Blockbuster. European charts are often barely distinguishable from American ones, because Europeans like American music.
Still, the fact is, that there isn’t much space left for things that aren’t American. So when people are happy that Americans don’t factor into the Eurovision contest, they aren’t saying “Thank God, there’s no America, we hate America”, they are saying “Hey! No America for once! Let’s see what everyone else is doing!”
If you call that bigoted, you really have no understanding of the pervasiveness of US-American culture in most of Europe.
