Europe in general is a lot more racist than the US. For all it's racism, black people are accepted as members of society and it is normal to see them. Nobody will stare at you, just because you are black. And in the US the problem of racism is aknowledged and discussed. Europeans will swear up and down that there is no racism and if there is, it is restricted to "a couple of idiots". You won't get into clubs and you will be treated with subtle contempt by civil servants, and the police. Living in Germany I have been stopped and searched by the police countless times. One time, I was on a train full of white people and the police walked straight up to me and asked to see my id. They controlled nobody else. The same thing happened when I stepped out of a plane at the airport. I barely set foot in the building when I was approached by two cops and asked for my id.
Hell, in Italy, black soccer players are regularly insulted by fans and players of the other team. A couple of them said fukk it and walked off in the middle of the game and some high ranking officials had the nerve to call them unprofessional instead of blaming the racist crowds..
