I thought that the story/article itself was quite nice. My concern was with the headline. Was it just for clicks that you put "Interracial" in there? I mean that fact had nothing to do with the story did it?
You could possibly have mentioned they were interracial in your descriptions of them but it was still not necessary.
I find that the fact that you had to mention that as disappointing. That would not have been an issue here in the UK and certainly not published.
It shows how hung up America is on race.
