He wonders why his family were stared at -- then says "oh we're a different color" -- that's what people do, as long as the stares were not hostile, big deal. However, he never said it was racist
Then, he says: "superb cultural heritage of Sweden" -- hardly sounds racist
Yet, he points out two things:
The first probably was a misunderstanding, but the second seems plain rude
He doesn't scream or even say it was definitely racist, he just points out his experience
He doesn't go around calling people "racist"
