Another Question About Questions

A recent conclave of the 3-umm-egos, whereat two of the members convened telephonically without proper notice given to the third, it was settled that rhetorical questions ought to be punctuated with question marks. Period. The debate is closed.

Unless of course, the absent member demands a reconsideration on the grounds that the meeting was procedurally invalid.

Now, that that is settled, would everyone please start complying with the rule to use question marks at the end of all questions, even rhetorical ones.
