Considerate communist and family (7)
I believe the answer is:
kindred
'family' is the definition.
(thesaurus)
'considerate communist' is the wordplay.
'considerate' becomes 'kind' ('kind' can be similar in meaning to 'considerate').
'communist' becomes 'red' (red is a kind of communist).
'kind'+'red'='KINDRED'
'and' acts as a link.
(Other definitions for kindred that I've seen before include "Affinity" , "Family and relations" , "Relatives" , "Family - like" , "Closely related" .)
