Various nationalities have a 'look' to them, which gives a fair clue as to their nationality. Likewise when you hear them speak - no need for telepathy at all.
Most of us can work out from an accent, roughly where someone born in the UK is from, I certainly can and there is nothing racial about.
If someone was writing a book they would describe characters and scenes to capture the readers imagination.. same as if your telling a real story. No its not racist
