There are a great many people in this group who seem to compulsively 
respond to this guy in spite of the fact that he continues to post the 
same sort of denigration of Forth over an over again.  No matter how 
many people respond to him, he continues to not respond to any of the 
points they raise and post more of the same in reply.

Why do people keep responding to him?  Why do I bother to point out any 
of this?
