You'd be surprised. Since we seem to have moved to ad-hominem argumentation :
I think your categories and your political reflexes prevent you from thinking straight. Everybody in the world would have a broad understanding of what "french" means (or "japanese", "americans", "italian", etc). For some reason you pretend to ignore there are some cultural norms that are associated to a nation ("cultural" in the broadest sense, which includes the way you look). I believe because this fact scares you or have been associated to a taboo.
Those taboos prevent you from addressing questions, and not addressing the issues don't make them magically disappear. Worst, you risk leaving those questions to people that have a political agenda.
I've already had this conversation many times with people arguing against the obvious situation, and it inevitably leads to absurd conclusions that defy the immediate cognitive conclusions and intuition of anyone looking at a given city landscape (you could tell just by looking at a picture if a city looks european, african or asian, for example).
However this is most of the time a total waste of time, because the reason the person is arguing against the obvious is not because of intelligent caution, but rather out of scare.
So sorry if i'm not going this route with you. If you're sincerely curious i suggest you go on a bike ride in Argenteuil on a friday.
not sure you understood my point. I rely on immediate cognitive understanding of what "french" means.
It's a mix of the way you dress, your body features (yes, skin color is one of them obviously but that's far from the only one), your language, all your daily habits, the food you eat, author you've read, etc.
It's the general picture people have in their mind when they think of an archetypal "french". Doesn't mean all french are like that, obviously. Much like i'm pretty sure you could find japanese with natural blond hair who never eat raw fish.
You may also argue that this image of french people is completely outdated, and that the metropolitan french population has evolved in the past 50 years. But that's precisely my point.
