They favour youth, eg, as it’s fantastic! (7)

I believe the answer is:

ageists

'they favour youth' is the definition.
(people who discriminate against the elderly)

'eg as it's fantastic' is the wordplay.
'fantastic' is an anagram indicator.
'eg'+'as'+'its'='egasits'
'egasits' anagrammed gives 'AGEISTS'.

I've seen this clue in The Times.
