I assume they're referencing the not very subtle visual that a single mother with a mixed race child is the face of Europe. I suppose the argument is that since they only picked a single image to convey "The EU Voice", that's an intentional choice.
I'm not European so I guess I don't care if their culture is supplanted. But maybe they do.
I'm not sure what culture you think may be supplanted here. If it's the culture of "a classic white mother holding a darker baby can't represent us", then I can't wait for it to be supplanted.
You could have saved a lot of typing by leaving it at this and saying what you meant. No reason to be coy any more. The quiet part is being said out loud now.
I honestly had no idea what the original commenter was even talking about before I started reading replies, which in hindsight was a mistake.
