Even without exception, old-fashioned in their views (3,6)
I believe the answer is:
all square
'old-fashioned in their views' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'even without exception' is the wordplay.
I cannot quite understand how this works, but
'even' could be 'square' (I've seen this in another clue) and 'square' is found in the answer.
'without exception' could be 'all' (I've seen this in another clue) and 'all' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for all square that I've seen before include "like fuddy-duddies, without exception?" , "Equal in rectangular way?" , "Quits" , "Level" , "Of debts, settled" .)
