Important scriptures make people opinionated (6)
I believe the answer is:
bigots
'people opinionated' is the definition.
I can't tell whether this defines the answer.
'important scriptures' is the wordplay.
'important' becomes 'big' (synonyms).
'scriptures' becomes 'OTs' (OT is short for Old Testament).
'big'+'ots'='BIGOTS'
'make' is the link.
Can you help me to learn more?
(Other definitions for bigots that I've seen before include "Racists" , "Sectarians" , "Intolerant and prejudiced people" , "Persistently prejudiced persons" , "Intolerant, prejudiced persons" .)
