The point of those assosiated symbols though, is to take them over, and make them your own. Which is exactly why you'll hear women using the "b" word regarding their own personality, or as a more obvious example here...
The idea of having clothing and styles, books and languages reserved only for certain groups is a frightening one for me, as well as potentially dangerous. As much as I do value groups and respect the right to maintain essential aspects, I also feel that a major component is one of sharing them. It's like, saying that the French can only have French fries, and if they're to be truly American, you have to rename them. The French language, isn't even reserved for France either, as you've cited as an example. I'm Canadian, and it's another official language here, and a vital part of our country's history. That doesn't mean that when I attempt to speak the language, I'm somehow trying to be French, but I think that it's not a positive idea to only allow "true Francophones" access to that aspect.
