Boycott is no way to face discrimination (9)
I believe the answer is:
ostracism
'boycott' is the definition.
(thesaurus)
'is no way to face discrimination' is the wordplay.
'is no' becomes 'o' (resembles 0 - 'no' can mean 'zero').
'way' becomes 's' (Compass direction - South).
'face' indicates taking the first letters.
'discrimination' becomes 'racism' (racism is a kind of discrimination**).
The initial letter of 'to' is 't'.
'o'+'s'+'t'+'racism'='OSTRACISM'
(Other definitions for ostracism that I've seen before include "transferring to Coventry?" , "cold shoulder" , "Refusal to associate with, exclusion from society" , "Exclusion from a group or society" , "Banishment" .)
