When you originally posted this, as supporting documentation, you linked us to an anti-AB???? website. As your wording exactly matched some of theirs (seemed to be cut and pasted) it was (and is) logical to assume that it was the source of knowledge for your post. It was certainly presented as fact, and it certainly did not come from an unbiased source. What other conclusion should we come to?

I confess that I can't currently open the pdf you link me to now, so I can't do the research to determine if it is more anti- stuff or if it represents a balanced view. I'll have to try to open it from home, tonight.
