Yes, it is true that you can get rid of an accent, and that you can overcome certain limitations that arise out of the 'state of affairs of the world'. I do not deny this.
Yet, sometimes you need a lot of effort to overcome certain obstacles. Perhaps I am somewhat inefficient with my efforts, and I should try harder. Or at the very least, consider asking for a tutor. In spite of that, I hope that you understand that we do want to blend in, and just like 'fat people', we sometimes lack the tools to appropriately do so.
So, in conclusion, I do not disagree with what you say, but I'll choose to focus on the actual actions that I can take to communicate more effectively. Right now, that means finding coaches that help with pronunciation.
