The teacher in question said he was just trying to be "Colorful". Really Mr. Teacher? It was absolutely unnecessary in my opinion and unfortunately, this poor choice will affect your future career.
Is this just stupidity or he had some kind of personal reason to become "Creative" in this way? Is a strange story. I agree anyway that his career should suffer from this. Is not acceptable when somebody tries to include into normality characters such as a serial killer or a pervert. Is like telling the students that they are normal figures and that they should be welcomed as part of our everyday life. Schools are the primary tool for education and opinion forming: what is taught inside should be carefully selected and filtered.
