The obvious difference is that the acts you listed are illegal and done without the consent of the victim.
Well, there is a serious problem with the terminology - and that is actually at the root of the whole problem. Are these acts or are these orientations? Let's deal with homosexuality - is it an act or an orientation? Does an act have to be involved for homosexuality to exist as an entity? If the definition of homosexuality is 'attraction to a member of the same sex', than that means that the whole thing can only exist in one's mind (since by definition, attraction can only exist in the mind). Imagine that - all of this stupid same-sex legislation Canada has now blindly barged forward on is geared towards some stupid self-identification and and self-declarations that have nothing to do with what a person does? What would a means test be for homosexuality? On those grounds, pedophilia, bestiality and necrophilia or any other 'feelings' that one may have should gain equal standing, no? What about all those that managed to put homosexual thoughts aside and go 'straight'? I would submit that there is no such thing as homosexuality - there are are only acts of homosexuality and the same goes for all these other 'orienations'. As a matter of fact, I would submit there is only sexuality - and beyond that, there are normal and perverted acts as to how one's sexuality is manifested. And by the way, that's not just my thoughts on the matter, that's scripture.
