Idolater is disposed to get opinions on paper (10)
I believe the answer is:
editorials
'opinions on paper' is the definition.
(opinions in a newspaper)
'idolater is disposed' is the wordplay.
'disposed' is an anagram indicator.
'idolater'+'is'='idolateris'
'idolateris' anagrammed gives 'EDITORIALS'.
'to get' is the link.
(Other definitions for editorials that I've seen before include "Newspapers' opinion columns" , "Leaders" , "Leading articles" .)
