Much ado about straw- Colossus of Rhodesism
All US Presidents are addressed as "Mr. President" - for life. Ditto Judges, many military, oodles of "Doctors", Professori Emeriti yada.
Once, ever a "Rhodes Scholar" - as assuredly, a "Rhodes Scholar" in perpetuity.
(Did his scholarship / scholarliness cease to exist at the end of some time period?)
Pshaw, or as Bill the Cat sez
Ack Phhhhbbbbbbtttttt
