Doctrine bothering aimless cur (10)

I believe the answer is:

secularism

'doctrine' is the definition.
(secularism is a kind of doctrine)

'bothering aimless cur' is the wordplay.
'bothering' indicates an anagram.
'aimless'+'cur'='aimlesscur'
'aimlesscur' is an anagram of 'SECULARISM'.

(Another definition for secularism that I've seen is " Belief in excluding religion from state functions".)

I've seen this clue in The Telegraph.
