Communist circles reasonably satisfied (8)

I believe the answer is:
requited
'satisfied' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'communist circles reasonably' is the wordplay.
'communist' becomes 'red' (red can informally mean communist).
'circles' indicates putting letters inside.
'reasonably' becomes 'quite' (I can't justify this - if you can you should give a lot more credence to this answer).
'red' placed around 'quite' is 'REQUITED'.
Can you help me to learn more?
(Other definitions for requited that I've seen before include "Repaid appropriately" , "Returned as love may be" , "Paid back" .)
