We all have our prejudices. Yes, including you.
We see a movie that's historically correct and shout: 'Hey, that's not right! He's a Scotsman so he should wear a kilt!' When the story is situated before the 1600's it's absolutely correct. And you are wrong.
Thing is: the media have so much power over us that we rather believe Hollywood filmmakers than our history teacher. Name the first three things that come to mind when you think of Holland and once more answer the question: 'Are you prejudiced?'
