Sometimes as a reflection, I think it is interesting to think about the word pedophile as the way it is used. I've seen a lot of talks over on the french internet of it's use and a very slow switch towards the use of pedo-criminal. Which I think it is interesting to bring the criminal notion into it BUT it is used specifically because of the meaning of pedophilia in ancient Greek and I'm not so sure about keeping the part that means children in it.
Pedo - philia would translate to children and love, but specifically the friendship kind of love. Which would basically say that this mean the one who loves children as friends, which yes it can be questionable that this is the one we use to talk about such vile crimes. We could swap the prefix philia for rastre but it is used as a slur for gay men in french and it has a meaning in that language ( attraction towards underage boys ). Simply calling them groomer wouldn't work either because not all pedophiles will groom their victims.
Ultimately I don't think anything will be able to replace pedophile, it is very ingrained in society. But it is very important to keep on discussing and thinking about the meanings of the words we use and what lays behind them.
