I find your question very particular, my friend, @ DarthCoin which we are debating from many perspectives (due to the different comments). Certainly we are owners of our names because as thinking beings we decide so, but not because someone forces us to use it, according to UNICEF, the name is a full human right and cannot be seen as a concession. Its repercussions are as immediate at the birth of people as they are persistent in their daily lives. However, can't I call myself whatever I want, regardless of the system or state that supposedly governs that?
