I believe the answer is:

barb

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

'there's little point in removing' is the definition.
I can't judge whether this definition defines the answer.

'it from rabbit stew' is the wordplay.
'from' indicates named letters should be taken away.
'stew' is an anagram indicator.
'rabbit' with 'it' removed is 'rabb'.
'rabb' is an anagram of 'BARB'.

Can you help me to learn more?

(Other definitions for barb that I've seen before include "Small prong on larger point" , "Arrowhead projection" , "Part of an arrow head" , "part of a habit" , "Thorn or spike" .)
