Although I respect your opinion, that is definitely not my experience

I am of French descent, but have never lived there, and travel to France, Spain and Switzerland often. I was last there three months ago and will be there end of July for the Olympics.

I have never smelled anyone from Asia, Europe, Latin America, or Oceania that smells anywhere near some of the smells you get from some people of African descent, Senegal, Algeria, etc.

Just my two cents

Edit: Just to clarify, there are millions of dark skinned French and British people that do not share this characteristic. I believe this smell is purely cultural
