“Regardless of the context”? Context means a lot. Listening to a speech of Adolph Hitler in a politics class is very different from listening to the same speech in a meeting on the “Jewish problem.” It would seem obviously relevant to a discussion of the civil war to show the respective flags.
Hart was the subject of an earlier complaint over a comment that he made with regard to lynching. Yet, the statement of the board seems to treat any showing of the confederate flag is a form of hate speech. What do you think?
