Millennials in support of avoiding kids (3,1)

I believe the answer is:

gen y

'millennials' is the definition.
(Gen Y can refer to the millennial generation)

'in support of avoiding kids' is the wordplay.
'in support of' becomes 'pro'.
'avoiding' indicates named letters should be taken away.
'kids' becomes 'progeny' (a person's offspring).
'progeny' with 'pro' taken out is 'GEN Y'.

I've seen this clue in The Hindu.
