Prejudice a tad removed from amateur dramatics (6)
I believe the answer is:
racism
'prejudice' is the definition.
(I know that racism is a type of prejudice)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for racism that I've seen before include "A basis for hate crime" , "Prejudice regarding ethnicity" , "Prejudice against people of different origin" , "Ethnic discrimination" , "Nazi-style discrimination" .)
