I'm a little stuck... Click here to teach me more about this clue!

'or lacking in balance' is the definition.
I can't judge whether this definition defines the answer.

'oscar denies adaptation is primarily discriminatory' is the wordplay.
'oscar' becomes 'o' (phonetic alphabet: alpha, bravo, charlie etc.).
'adaptation' indicates an anagram.
'is primarily' indicates taking the first letters.
The first letter of 'discriminatory' is 'd'.
'denies' with letters rearranged gives 'neside'.
'o'+'neside'+'d'='ONE-SIDED'

Can you help me to learn more?

(Other definitions for one-sided that I've seen before include "Unbalanced" , "So denied being partisan or unfair" , "Partial" , "Unfair or uneven" , "Unfairly biased" .)
