Not every pedophile is a rapist.

[Angrboda]

Because a fetish is getting sexual gratification from a particular scenario or object, while a sexual orientation is the gender you are attracted to. That's not "semantic", they're very different things.

This is nothing more than a case of self serving definitions. Traditionally acknowledged sexual orientations involve sexual attraction to a sex or sexes. That is not what makes it a sexual orientation. If we're to set the traditional orientations in brackets and ask what makes them unique above and beyond pedophilia, presenting a definition of sexual orientation that can only apply to traditional sexual orientations is simply sidestepping the question. I could equally well argue that a sexual orientation is a non-volitional attachment to a particular class of individuals as objects of sexual gratification, and thereby side step your self serving definition. All you've done is make more semantic distinctions.

Liking the feeling of being in power over someone helpless during sex is not a sexual orientation.

What is your evidence that this is the primary gratification for the pedophile? How do you know that a pedophile doesn't feel genuine sexual attraction to children?
