Dutch flag offensive?

The Dutch flag has been banned by a school in the Netherlands:

Cals College in IJsselstein has prohibited two of it's students to have Dutch flags on their bags.

The 16 year old boy and his friend where told by the director of their school that they "urgently should consider" to remove the Dutch flags from their bags, it could provoke other students, mainly Moroccan students. The two considered the urgent request of the school as a prohibition.

And it seems that the Dutch media are as politically correct as their American counterparts:

In a radio interview, one of the boys was asked if he was a racist. He denied and told the reporter that his mother was black. When he was asked about the incident that lead to the prohibition he explained that he had some verbal exchange with a Moroccan boy during competition swimming. As a result a group Moroccan then threatened him on school. At that moment the boy went to the school director.

It is strange to think that some day the American flag may be banned from schools in the United States in order to appease immigrant groups.
