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You may also argue that this image of french people is completely outdated, and that the metropolitan french population has evolved in the past 50 years.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.
What are the words you are scared of using if you answered this question?
Why won't you use them?
