Love God? Explain racists or suffering for starters! (4)
I believe the answer is:
eros
'love god?' is the definition.
(Greek god of love)
'explain racists or suffering for starters' is the wordplay.
'for starters' says to take the initial letters.
The initial letters of 'explain racists or suffering' is 'EROS'.
(Other definitions for eros that I've seen before include "Arrow-shooting god" , "capital statue" , "Pagan god" , "very centre of London?" , "Roman god of love, Cupid" .)
