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

'mass objections' is the definition.
'demonstrations' can be an answer for 'objections' (demonstration is a kind of objection). I'm not sure about the 'mass' bit.

'devil and saint sort out' is the wordplay.
'devil' becomes 'demon' (synonyms).
'and' is a charade indicator (letters next to each other).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'saint'+'sort'='saintsort'
'saintsort' with letters rearranged gives 'strations'.
'demon'+'strations'='DEMONSTRATIONS'

Can you help me to learn more?

(Another definition for demonstrations that I've seen is " protests".)

I've seen this clue in the Sydney Morning Herald.
