I believe the answer is:

disharmony

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

'conflict' is the definition.
(I've seen this before)

'appealing about e g gun running in' is the wordplay.
'appealing about e g' becomes 'dishy' (I can't explain this - if you can you should believe this answer much more).
'gun' becomes 'arm' (I've seen this in other clues).
'running' becomes 'on' (eg when a machine is running it is on).
'in' means one lot of letters goes inside another.
'arm'+'on'='armon'
'dishy' going around 'armon' is 'DISHARMONY'.

Can you help me to learn more?

(Another definition for disharmony that I've seen is " conflict".)

I've seen this clue in The Telegraph.
