After we have discussed this matter extensively Walter and I decided to 
move forward and undo this language change.

It's a judgment call. The advantages and disadvantages of this have been 
discussed extensively. We are accountable for decisions like this, and 
we must make the decisions we believe are right. That said, making a 
decision when there are strong feelings and opinions on both sides is 
always difficult.

We would really like to find consensus, but failing that, request your 
indulgence.
