Geneva is something like 0.1% black. If in 5 years of buying drugs, you find that ~80% of your dealers are black, then I think you can make the assumption that most drug dealers in Geneva are black. I don't see that as racism - that's just a statement of fact.
Now, if you carried that one step further and said that black people in Geneva are probably drug dealers, then yeah, that's racist...
that was not the intent... those guys have probably some tough lives behind them and no future here, living often without permit on the fringe of society. it's just that meeting them in dark alleys after dark, being surrounded by suspicion etc. ain't activity I do for pleasure or some weird kick out of it; just a necessary evil.
But there is no reason not to point it out. He made an observation about the drug dealers in his area, and mentioned it. I don't see why there would be anything more to it than that.
