Inside complex activism is demand (5)

I believe the answer is:

exact

'demand' is the definition.
(exacting is a kind of demanding)

'inside complex activism is' is the wordplay.
'inside' indicates a hidden word.
'EXACT' is hidden in the letters of 'complex activism is'.

(Other definitions for exact that I've seen before include "Demand payment" , "Precise, accurate" , "Not approximate; inflict (revenge) on someone" , "Precisely accurate" , "without rounding" .)

I've seen this clue in The Irish Times.
