You suggested "Hogan's Heroes" was the source, without considering the real source.
Many would consider that irresponsible. After all, the source is given so people can evaluate the credibility of the post. To ignore the real source and say that "Hogan's Heroes" was it seems a bit over the top.
There is much that is known by people who have spent their lives studying some issues that is not known by people who depend upon Conservative blogs for their information. Or TV serials.
I realize that is an unwelcome shock. I'm also sure you can rationalize it.
