==Referendum on streaming after 4th or 6th grade== 

 I removed the part about the referendum done in Hamburg if students should be streamed after 4th or 6th grade. This does not involve the Realschule (which would have been abolished not matter which outcome the referendum had) and thus is not the topic of this article. I copypasted this into Education in Hamburg. 
 I removed also some personal opinions an editor inserted about persons he did not agree with. He or she called their arguments "bizarre" and "a classic example of fighting-for-peace-and-f*cking-for-virginity logic". While everybody is welcome to think of other peoples opinions as bizarre or illogical, Wikipedia articles are not the right place to express those feelings. This is not a blog or bulletin board.
