Do you think Scottish people are racist?

I’m know a guy who is Scottish, his attitude around the white folks is very loving, respectful, but when I see him interact with the brown people, he becomes arrogant, he acts annoyed by them, talks is a very disrespectful manner to them as if he is better than they are. I’ve met a few of his friends and sometimes they act the same way. So I don’t know if this is matter of race or if it’s just the way they are.
