I think it is important form us to recognize and accept that this is 2010.

The Constitution means what ever the speaker needs for it to mean, or
can be dismissed outright.

014 means what ever the speaker needs for it to mean.....

It is the duty and responsibility of the hearer (or reader) to figure
out how it applies to them for the moment.

Standards and agreements on protocol are so eighteenth century.
