What Name Should I Answer To?

Recently in Ireland there seems to be an urgency for people of African descent to not only need  but to want really badly to have an umbrella name for themselves.  Go into most public places in small or

Who?

even large numbers and the question asked is "So what do we call you?"  Its a very loaded question and I don't know whether it's intrigue, curiosity, ignorance or pure laziness that's propelling this question to be thrown around.  You see I grew up in a country which is inside a continent and I never used to define who I was beyond my name most times.  Sometimes my surname would come in and other times where my father's ancestors were from with people asking for the exact place since from my words and accent there would be no mistake that I am Karanga.  Kkkkk! That's taking you quite deep I know unless you are Zimbabwean and you get what that means.  Since moving to Ireland I just say I am Zimbabwean and that's it.  Few times people with a broader understanding of the country would ask are you Shona or Ndebele and though I respond the response if you are Zimbabwean is as verge as saying I am African.  It means a lot and it also means nothing.
