Do you think anybody can make heads or tails from this text where you
removed all references to context without even marking these changes?

It was a very bad idea to edit this text in such a way.  Crippeling my
text in such a way is something which makes me actually really angry.
It gives the words a different meaning, and I will not accept this.


Why don't you simply provide a reference to the respective postings in
the list archives, so everybody can actually understand what you are
talking about?
