As interesting as needless pedantry is, it may worthwhile moving this
discussion or being more constructive.
If the discussion is to continue I would recommend you both hash out exactly
what the structure would be and stop metaphorically attacking inanimate
You both obviously have a lot of input, maybe you can find where the conflicts
are and then bring those conflicts forward for the community to observe and
possibly comment on.
This is just my opinion of course but it seems obvious the discussion is not
progressing very rapidly.
