That is completely true and fascinates me. If you go to any city centre, train station, etc. in Europe, you will find lots of black people just... doing nothing. They are just there, sitting, perhaps alone, perhaps many of them. They aren't even talking or doing anything, they just stare into the distance. They are part of the scenery. I have no idea what this means, who brought them here, what they actually do (if anything), and who's going to take them away (and when).
