Would it have been a better parody if the child had been black? We ARE getting to be too sensitive. Would this child become the next Hitler and follow through with a world hate movement? Hmmm ...
People have their own beliefs, but teachers/educators often get to be the deciders of what's right. Unless parents complain, I guess. The way social media works, teacher shaming is a little like cop shaming. Deserved or not.
In middle school we had to write a long paper on someone historical, who had great influence. This was a liberal educated school in a "good neighborhood". Queue up the papers on Amelia Ehrhardt or FDR. One kid wrote his paper on Hitler. I wanted to write mine on Karl Marx but was told by the teacher I couldn't because "he was evil and the person we wrote about had to have a positive influence" or some such.
Getting thousands of people to believe in your ideology isn't positive? That's what's screwed up about this country? No one cares to look deeper. Just believe.
