Being prejudiced, I depart in shocking debt (7)
I believe the answer is:
bigoted
'being prejudiced' is the definition.
(I've seen this before)
'i depart in shocking debt' is the wordplay.
'depart' becomes 'go' (synonyms).
'in' is an insertion indicator.
'shocking' indicates anagramming the letters (I've seen this in other clues).
'i'+'go'='igo'
'debt' anagrammed gives 'bted'.
'igo' going within 'bted' is 'BIGOTED'.
(Other definitions for bigoted that I've seen before include "I go into debt, being prejudiced" , "Refusing to listen to reason" , "Dogmatic" , "Obstinate" , "Not to be persuaded" .)
