Good question.Attacks, isnt this language a bit strong?
I agree with dolphin (Flipper).
For example, Kloppo (Jürgen Klopp, manager of Liverpool FC, a soccer club) uses the word all the time. If that was considered offensive by those folks, they would have canceled and boycotted the premier league and that would have made it into the media. That is the most attractive league of sports worldwide.
To the topic:
I wonder how they teach history at school (not university). We watched speeches of Hitler and read quotes of the Nazis. I dont think that these books that they want to boycott are worse.
The only important thing is. That you have a commented version at school (or the teacher comments it). So that you dont drift into racism. So you have to explain, why it is wrong.
