Nobody's location is on view unless you look at profile - I get it too - 54% of users are American so I think everyone thinks that most people are from America, I get it as well and I leave my username up.
No, you can just say you aren't American instead of ruining anon for everyone else. Or just don't go anon... for a short while exact ages were posted with anon posts, that was telling enough. Country if origin would be the same. Most anons don't have this issue so it doesn't make sense to change the rules for you.
I believe everyone's ASL (age range, sex, location) should be visible, even when anonymous and private profile. One can't give a real satisfying answer without a bare minimum of basic knowledge about the asker. Sex is visible by the color but 10% of men have some problem trouble seeing colors. That isn't perfect either thus.
