Intolerant people try to get involved in scraps (6)
I believe the answer is:
bigots
'intolerant people' is the definition.
'try to get involved in scraps' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'to get involved in' indicates putting letters inside.
'scraps' becomes 'bits' ('bit' can be a synonym of 'scrap').
'go' put within 'bits' is 'BIGOTS'.
(Other definitions for bigots that I've seen before include "Persistently prejudiced persons" , "Intolerant, prejudiced persons" , "Sectarians" , "Intolerant and prejudiced people" , "Racists" .)
