Just because someone relates to a group of people it does not mean that they are the same.
Similarly, German people have suffered some similar prejudices. There have been instances where someone from Germany has been accused of being racist or even being a Nazi. The kindest person could be treated awfully solely due to an accent.
These occurrences are more unfair than anything else. Kind, innocent individuals have done nothing, yet are targeted due to their accent or appearance. They have done nothing to gain a bad reputation, yet are stuck with this burden.
