Bigotry perhaps that’s not tasteless? (14)
I believe the answer is:
discrimination
'bigotry' is the definition.
(thesaurus)
'that's not tasteless?' is the wordplay.
I cannot quite understand how this works, but
'that's' could be 'sc' (short for Latin scilicet- 'it follows' or 'that is) and 'sc' is found within the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
This explanation may well be incorrect...
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for discrimination that I've seen before include "bias" , "coming to judgment" , "Good taste" , "display of prejudice?" .)
