"I am not racist or anything, but 100% of them in Geneva are black - that's 5 years of experience"
...it doesn't seem far of a stretch to make the leap to using your statement here to indicate that you may in fact be racist.
There was no reason to indicate their race, so why do it? Did they have blue eyes, too? What can I infer from shady blue-eyed people on street corners selling me drugs?
