If two twin sisters who are both 18 years old and they both want to marry eachother I think legally they should be allowed to do it because what they’re doing isn’t hurting anybody.
If a brother and a sister who are both consenting adults and they both want to marry eachother I think legally they should be allow to do it as long as the brother gets a vasectomy so that they do not have any kids together. Because what they’re doing isn’t hurting anybody.
I agree that incest is weird and gross which is why I personally would never do that but I don’t think that it’s morally wrong as long its between siblings that are both consenting adults and they do not have any kids together because what they’re doing is completely harmless and isn’t hurting anybody. So they deserve to have the right the right to marry eachother if they want to just like everyone else that isn’t related to their spouse.
I’m arguing both sides here in different comments.
You’re right, logically it seems silly at first glance. The basis of nearly all our laws is “If harm to another, then some harm to you.” So if close relatives, a Brother and Sister in this example, were to be each other’s Prom Dates into the late evening, and no one knew they were related, do we actually hear that tree fall in that forest?
Probably not.
So thus they have harmed no one.
So why?
I think because collectively we have an innate understanding of who we are closely tied to by blood we base our laws off the majority rule. At a glance there is nothing wrong with the act. I’ll even argue it happens far more than we know, though also far from being common.
So then it becomes a question of culture. Laws exist as paths that guide a society. Without it the very significant number of people who could do something because they have a different moral code, but don’t because they want to follow the law, would then be free to act without restriction. Besides, as I said in another reply: It is less about others in this case and more about the two doing the act and the potential to bring in a child who should never have had anything to do with it in the first place.
Anyway, I’m interested to hear other arguments. No reason we can’t discuss either way. Though I doubt it’ll bring some great revelation.
I’m very much for the idea that if you are not causing harm to others, and it’s just something you choose to do with another consenting adult, go for it. However, that is not true for incest where a child can be produced, as there is demonstrable evidence that it will harm the child and any of that child’s children. So if there is no possibility of a child being produced then I honestly don’t give a shit what messy bits get shoved into each other in someone else’s house.
