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 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.
