Sorry if this caused any confusion. Your response to my original post questioned my asertion that its very hard not to have an accent, so in my last post I was trying to flesh out my definition of 'not having an accent.' As I stated in my last post, to me, not having an accent amounts to being 'indistinguishable from a native speaker.' If your definition is something different, which it appears it is, then we arent really arguing about anything, just have different definitions. Everything in my post was to say its very very hard to become indistinguishable from a native speaker. Sorry if I caused you to read it in any other way.
