I wrote that it's "extremely rare". The subsequent "never happens" was not meant literally, which I expected to be obvious to anyone reading the entire comment.
Of course, this happens everywhere around the world. I'm not arguing whether or not it happens here, but to what degree. And it is self evident that the degree to which minorities are discriminated in Europe is magnitudes lower than in the USA. Europeans may have invented racism, but Americans sure have since perfected the craft.
Perhaps you're right about my proposal being a potential source of serious issues. I can't say it's not at all possible. However, my main point here is not to apply American standards to the European Union. It's like saying that restrictions on ICE vehicles in Canada won't work, because the same policy wouldn't work in Eritrea.
