Ok, I'm not really arguing the negative connotation; I'm trying to understand the extremity of the reaction. Because in my mind it doesn't really connect.
Hitler was real; he lived 70 years ago.
Shylock was fictional; he was created 400 years ago.
Hitler persecuted millions of Jews.
Shylock was a Jew who argued for his own humanity.
Yes, Shylock was portrayed as a villain, but he lived in an obviously prejudiced society...
