Intolerant person (5)
I believe the answer is:
bigot
'intolerant person' is the definition.
(someone with bigoted views)
This is all the clue.
(Other definitions for bigot that I've seen before include "Dogmatist" , "Someone intolerant of opinions of others" , "Fanatic" , "One is prejudiced and intolerant" , "Racist or sexist?" .)
