Okay so I got into it on twitter about the Nightwing movie announcement that they are casting a wide net to find the right actor for the job.
Someone responded with "hopefully that includes poc" which I took to mean african american (my mistake) but in me defense there was a discussion a few years back about poc being the preferred nomenclature for African American people as a whole.
My immediate knee jerk response was "But he's white" I started reading in 2003 and though I haven't read much Nightwing I did read for a couple of years and never once was the Romani part of his back ground brought up.
Does it make sense that boy who grew up in the circus would be 1/4 Romani? Absolutely but that's not the character that was created and it has been largely ignored since it was introduced/retconned.
