It will be an interesting experiment since the vast majority of Americans have none of these stereotypes. The word Gypsy conjures solely the image of a palm reader and the word Roma means nothing to the vast majority.
Their speech will sound like Russian to the American ear and their appearance will match that impression.
So, if the trend somehow continues or expands, we have a chance to see whether the exact same stereotypes re-emerge or whether they too end up following an unremarkable integration trajectory.
