OK, here's one British person who refers to themselves as European. As that's probably not enough for you to win Today's Dumbest Comment on Hacker News, here's one of the above actors who definitely considers herself European:
Hah - well you made a point with your links that I didn't want to bring up, but since you did: the only people calling themselves "European" are people who really detest the idea of Brexit. But let me ask you something, what possible question could you be asked about yourself that would result in the answer "European". Here let me try:
Where are you from?
> "Europe" is too vague, people want country or city.
What would your cultural heritage be?
> Again, "European" is far to vague. Mine's English and Irish.
I'm really struggling here...
Again, if I didn't make myself clear: the use of the term "European" is entirely political (pro-EU).
