Well I guess you'll have to 'educate' the entire UK media and population into the nuances of the greek language...That is irrelevant.
It is a word with a specific meaning - "little kiddies" if you want it simplified.
That does not detract from the seriousness of the offences.
If you want to use Greek words for things then SirGalahad has furnished you with the correct one - ephebophile.
Although could you define 'little kiddies'?
Is there an actual specific age when all individuals reach puberty rather than a legal one?
And what about mental age?
Maybe you could then explain to the population that the sexual assault of a girl or boy aged 11/12 isn't the action of a pedophile?
(Gary Glitter thus wasn't an active pedophile, but Saville was)
So good luck with that!
PS. Could you also explain why the role of a pediatrician is to treat children up to the age of 16?
