Sorry that the Special Ed situation had to end this way, but unfortunately there are none so blind as those who will not see. When I was working at Border's the most frequent cases of in-store harassment were perpetrated by well-meaning folk of his ilk, in just such a manner.
HIV and AIDS has taken scores more puppeteers than just the late great Richard Hunt, unfortunately. Those of us who were in the business lost many, many mentors in the late 80's. Without hating anybody involved, I HATE that disease!
On the Africa subject, I don't remember who started it, but there was a great political debate among the African governments about the HIV/AIDS connection (somebody claiming it didn't exist.) I can't imagine how Sesame Street could respond to that, but did it come up?
